I cannot draw here.
but the graph of f(x) = |x| is a big "V".
on the negative x side it is a line diagonally from the top left to the origin (0, 0), and on the positive x side it is a line diagonally from the origin (0, 0) to the top right.
now, f(x) = |x| + 3 is then the whole (otherwise unchanged) graph of |x| shifted up by 3 units. and the "V" vertex is then at (0, 3) instead of at (0, 0).
URGENT A bakery wanted to make their muffins more uniform in size. They reworked their equipment to do so. To test the changes, they made 25 muffins then measured each one. Which of the following should they use to determine whether or not the equipment changes worked?
Select one:
a.
mean
b.
mode
c.
range
d.
interquartile range
The bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.
To determine whether the equipment changes made by the bakery have resulted in more uniform-sized muffins, they should use the measure of variability. The most suitable measure, in this case, would be the range.
The range is calculated by finding the difference between the maximum and minimum values in a data set. In this scenario, the bakery made 25 muffins and measured each one. By finding the range of the measurements, they can assess the spread of sizes among the muffins.
Here's how they can use the range to evaluate the effectiveness of the equipment changes:
Collect the measurements of all 25 muffins.
Determine the maximum and minimum measurements.
Calculate the range by subtracting the minimum measurement from the maximum measurement.
If the range of the muffin sizes is smaller compared to the range before the equipment changes, it suggests that the modifications have resulted in more uniform-sized muffins. Conversely, if the range remains similar or larger, it indicates that the changes might not have effectively improved the uniformity of muffin sizes.
Therefore, the bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

A number cube is rolled. Event A is rolling an odd number, and event B is rolling a factor of 12. What is P(AU B)?
Explanation:
A = set of odd numbers = {1,3,5}
B = set of factors of 12 = {1,2,3,4,6}
A U B = union of set A and set B
A U B = {1,3,5} union {1,2,3,4,6}
A U B = {1,3,5, 1,2,3,4,6}
A U B = {1,2,3,4,5,6}
The set union operation combines two sets into one bigger set. Duplicates are tossed out.
There are 6 elements in the set A U B = {1,2,3,4,5,6} out of 6 faces of the number cube.
Therefore, the probability event A U B happens is 6/6 = 1 = 100%; i.e. it is guaranteed to happen. Each face of the number cube is either odd, a factor of 12, or both.
Side notes:
A U B can be read out as "event A or event B"; so P(A U B) is "the probability event A happens or B happens or both".A intersect B = {1,3} = values that are in both set A and set B at the same time. These are both odd and a factor of 12.What is an equation of the axis of symmetry of the parabola represented by y=-x^2+6x-4?
im giving brainliest!!
Answer:
Step-by-step explanation:
Take out a common factor of -1 from the first 2 terms
y = -(x^2 - 6x ) - 4
Take -6 and multiply it by 1/2 and square the result. Add inside the brackets
y = -(x^2 -6x +(-3)^2 ) - 4
y = -(x^2 - 6x + 9) - 4
Because you added nine inside the brackets add 9 outside the brackets
y = -(x^2 - 6x + 9) - 4 + 9
The reason you add 9 outside the brackets is because of the minus sign on the left of the brackets. Without that minus sign, you would subtract 9.
Result
y = -(x^2 - 6x + 9) + 5
Now what is inside the brackets is a perfect square
y= -(x -3)^2 + 5
The axis of symmetry is x = 3 (see the graph below)

Lugar geométrico infinito formado por un conjunto de puntos que conservan la misma dirección
Answer:
l lugar geométrico de los puntos que equidistan a otros dos puntos fijos {\displaystyle A}A y {\displaystyle B}B es una recta o eje de simetría de dichos dos puntos. Si los dos puntos son los dos extremos de un segmento {\displaystyle {\overline {AB}}}\overline {AB}, dicha recta, o lugar geométrico, es llamada mediatriz y es la recta que interseca perpendicularmente a {\displaystyle {\overline {AB}}}\overline {AB} en su punto medio.
La bisectriz cumple la propiedad de que todos sus puntos equidistan a los lados de dicho ángulo, convirtiéndose la bisectriz en un caso particular del lugar geométrico que sigue a continuación.
El caso de equidistancia a dos rectas paralelas, obtenemos que la paralela media es el lugar geométrico de los puntos que las equidistan. Se observa que, bajo el punto de vista de que las rectas paralelas se cortan en el infinito -se elimina, pues, la noción de paralelismo-, pasa a ser un sinónimo de la bisectriz, donde el ángulo ha tomado valor nulo.
Secciones cónicas
Las secciones cónicas pueden ser descritas mediante sus lugares de geométria:
La circunferencia es el lugar geométrico de los puntos cuya distancia a un punto determinado, el centro, es un valor dado (el radio).
La elipse es el lugar geométrico de los puntos tales que la suma de su distancia a dos puntos fijos, los focos, es una constante equivalente a la longitud del eje mayor de la elipse.
La parábola es el lugar geométrico de los puntos cuya distancia a un foco equivale a su distancia a una recta llamada directriz.
La hipérbola es el lugar geométrico de los puntos tales que el valor absoluto de la diferencia entre sus distancias a dos puntos fijos, los focos, es igual a una constante (positiva), que equivale a la distancia entre los vértices.
Una recta es un lugar geométrico infinito formado por un conjunto de puntos que conservan la misma dirección.
Descripción de un enunciado de un lugar geométrico dado
En este ejercicio debemos concluir que tipo de expresión se deriva del enunciado del lugar geométrico. Recuérdese que un lugar geométrico es un conjunto de puntos que satisfacen una característica dada.
Matemáticamente hablando, el lugar geométrico puede ser definido a partir de las definiciones de longitudes de segmento de recta:
\(AC = AB + BC\) (1)
Puesto que \(AB\) y \(BC\) tienen la misma dirección, entonces es posible aplicar las siguientes equivalencias:
\(BC = k \cdot AB\), \(k\in \mathbb{R}\) (2)
\(AC = r\cdot AB, \,r\in\mathbb{R}\) (3)
Al aplicarse (2) y (3) en (1) y simplificar la expresión, tenemos lo siguiente:
\(r = 1 + k\) (4)
Por geometría analítica tenemos que el lugar geométrico debe ser una recta, puesto que \(r\) y \(k\) representan un conjunto infinito de elementos. \(\blacksquare\)

what is the functions domain ?
what is the functions range ?
find the values of the function f(-5)= and f(-1)=
Answer:
domain: -∞ < x < ∞range: -∞ < y ≤ -1f(-5) = -2f(-1) = -4Step-by-step explanation:
Function values and the extent of the graph can be determined by reading the graph.
DomainThe domain of the function is the set of values for which the function is defined. It is the horizontal extent of the graph. The graph shows the function is defined for all real numbers.
The domain is -∞ < x < ∞.
RangeThe range of the function is the set of output values the function may have. It is the vertical extent of the graph. The graph shows the function can have any value no greater than -1.
The range is -∞ < y ≤ -1.
Function valuesFunction values can be read from the graph by locating the x-value on the x-axis, and following the vertical line to its intersection with the function graph. The y-value of that point is the function value.
f(-5) = -2
f(-1) = -4
Or, we can write the function definition based on the graph, and use that definition to find the values at specific points. The graph is of the absolute value function reflected over x and translated <-4, -1>.
f(x) = -|x+4| -1
f(-5) = -|-5 +4| -1 = -1 -1 = -2
f(-1) = -|-1 +4| -1 = -3 -1 = -4

Write the equation of the line in all three forms that is perpendicular to the line 6x+18y=36 and goes through the point (-5,4) Point-Slope Form, Slope-Intercept Form, and Standard Form
Answer:
Step-by-step explanation:
SLOPE OF THE GIVEN LINE
6x + 18y = 36
x + 3y = 6
3y = -x + 6
3/3 y = -1/3 x + 6/3
y = -1/3 x + 2
Slope = -1/3
slope of a perpendicular line = 3
POINT SLOPE FORM
y-4 = 3(x-(-5)
y - 4 = 3(x+5)
SLOPE INTERCEPT FORM
y-4 = 3x + 15
y = 3x + 15 + 4
y = 3x + 19
STANDARD FORM
3x - y + 15 + 4 = 0
3x - y + 19 = 0
Equation of line in point slope form is y-4= 3 (x+5), y=3x+19 is equation in slope intercept form and equation in standard form is 3x-y+19=0.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
6x+18y=36
18y=-6x+36
Divide both sides by 18
y=-6/18x+36/18
y=-1/3x+2
Slope of given line is -1/3, so slope of perpendicular line is 3.
The equation of line in point slope form with slope 3 and goes through the point (-5,4) is given below
y-4= 3 (x+5)
To find the equation in slope intercept form we need to find y intercept
4=3(-5)+b
4=-15+b
19=b
y=3x+19 is equation in slope intercept form.
The equation in standard form is 3x-y+19=0
Hence, equation of line in point slope form is y-4= 3 (x+5), y=3x+19 is equation in slope intercept form and equation in standard form is 3x-y+19=0.

What is the length of PQ?
14 units
17 units
27 units
34 units
The length of the line segment AB is 5 units.
Unfortunately, you haven't provided any information about PQ such as its location or any other data to help solve the question.
Therefore, it's impossible to determine the length of PQ using the given options. However, here is an explanation of how to find the length of a line segment using the distance formula, which may help you in solving similar questions in the future.
The distance formula is used to find the distance between two points in a coordinate plane, such as the length of a line segment. The formula is:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
where d is the distance, (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
To use the distance formula, you first need to find the coordinates of the two points that make up the line segment. Then, substitute these coordinates into the formula and simplify to find the distance.
For example, let's say you have two points: A(1, 2) and B(4, 6), and you want to find the length of the line segment AB. Using the distance formula:
d = √((4 - 1)² + (6 - 2)²)
d = √(3² + 4²)
d = √(9 + 16)
d = √25
d = 5
Remember, the distance formula can be applied to any two points in a coordinate plane to find the distance between them.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,003 was collected on the sale of 1,187 tickets. How many of each type of ticket were sold?
Therefore , the solution of the given problem of equation comes out to be 454 adult tickets and 733 student tickets were sold.
What exactly is a linear equation?The formula y=mx+b is used to produce a simple regression curve. The slope is B, and the y-intercept is m. Despite the fact that the previous line represents distinct components, the phrase "math equation blending several variables" is frequently used to describe it. In bivariate linear equations, there are just two variables. Application problems involving linear equations have no known solutions. Y=mx+b, usually known as mx+b, presents an easy-to-understand set of equations.
Here,
Let x be the number of adult tickets sold, and y be the number of student tickets sold.
The total number of tickets sold is 1,187: x + y = 1187.
The total amount of money collected is $3,003: 5x + 1y = 3003.
We can use the first equation to solve for x in terms of y: x = 1187 - y.
Substituting this expression for x into the second equation, we get:
5(1187 - y) + y = 3003
Simplifying and solving for y, we get:
5935 - 4y = 3003
-4y = -2932
y = 733
So 733 student tickets were sold. To find the number of adult tickets sold, we can use either of the original equations. Let's use x + y = 1187:
x + 733 = 1187
x = 454
So 454 adult tickets were sold.
Therefore, 454 adult tickets and 733 student tickets were sold.

What values of b satisfy 3(2b + 3)² = 36?
Answer:
The values of b that satisfy the equation are:
b = (2√3 - 3) / 2
b = (-2√3 - 3) / 2
In other words, b can take the values (2√3 - 3) / 2 or (-2√3 - 3) / 2.
Step-by-step explanation:
To find the values of b that satisfy the equation 3(2b + 3)² = 36, we can solve for b by following these steps:
1. Divide both sides of the equation by 3:
(2b + 3)² = 12
2. Take the square root of both sides:
√[(2b + 3)²] = √12
Simplifying further:
2b + 3 = ±√12
3. Subtract 3 from both sides:
2b = ±√12 - 3
4. Divide both sides by 2:
b = (±√12 - 3) / 2
Simplifying further:
b = (±√4 * √3 - 3) / 2
b = (±2√3 - 3) / 2
Therefore, the values of b that satisfy the equation are:
b = (2√3 - 3) / 2
b = (-2√3 - 3) / 2
In other words, b can take the values (2√3 - 3) / 2 or (-2√3 - 3) / 2.
