First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.
Let the number student tickets sold = x
Let the number adult tickets sold = y
7x+10y = 3888 -----------i
y = 4x-6 ----------------------ii
Substituting eq ii in i
7x + 10 ( 4x -6) = 3888

When the value of the y-intercept(b) change by subtracting a number from "b" in the equation "y=mx+b", the graph will move of shift down ? true or false
Answer:
True. The graph will shift down if we subtract a number from "b"
Step-by-step explanation:
"b" represents the y-intercept, or how high up on the y axis the graph intersects.
If we don't change anything except for the y-intercept, then the graph should only move up or down.
Because we are decreasing the value of "b" the y intercept will decrease, dragging the graph of y down.

What is a translation?In Mathematics and Geometry, the translation of a graph to the right simply means a digit would be added to the numerical value on the x-coordinate of the pre-image:
g(x) = f(x - N)
Conversely, the translation of a graph downward simply means a digit would be subtracted from the numerical value on the y-coordinate (y-axis) of the pre-image:
g(x) = f(x) + N
Since the parent function y = ∣x∣ was translated 4 units to the right and 9 units down in order to produce the graph of the image, we have:

Solve for θ if −10sinθ−8=5√3−8 and 0≤θ<2π.
The value of variable θ would be,
⇒ θ = 5π/3 and θ = 4π/3
We have to given that;
Expression is,
⇒ - 10sin θ - 8 = 5√3 - 8
Now, We can simplify as;
⇒ - 10sin θ - 8 = 5√3 - 8
⇒ - 10sin θ = 5√3
⇒ sin θ = - 5√3/10
⇒ sin θ = - √3/2
We know that sinθ = -√3/2 when θ = 4π/3 and θ = 5π/3 (among other angles).
However, since 0 ≤ θ < 2π, only the angles in the second and third quadrants are valid solutions for sinθ = -√3/2.
Therefore, the solutions are θ = 5π/3 and θ = 4π/3, option D is correct.

If a large smoothie takes 1 pound of bananas and 2 pounds of oranges, how much water would it take to grow the fruit?
The total amount of water required to grow the fruit for the smoothie would be approximately (239 - 287) gallons.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
To determine how much water it takes to grow the fruit needed for the smoothie, we need to use the information on water requirements for banana and orange cultivation.
According to the Food and Agriculture Organization (FAO):
Bananas require an average of 800 to 1000 liters (or 211 to 264 gallons) of water per kilogram of fruit produced,
Oranges require an average of 600 to 700 liters (or 158 to 185 gallons) of water per kilogram of fruit produced.
Now,
Assuming that the bananas and oranges used in the smoothie weigh 1 pound and 2 pounds respectively,
or approximately 0.45 kilograms and 0.91 kilograms respectively,
We can estimate the water required to grow the fruit as follows:
Water for bananas:
= 800-1000 liters/kg x 0.45 kg
= 360-450 liters, or 95-119 gallons
Water for oranges:
= 600-700 liters/kg x 0.91 kg
= 546-637 liters, or 144-168 gallons
Therefore,
The total amount of water required to grow the fruit for the smoothie would be approximately (239 - 287) gallons.

e^x=10^(x-1)
Answer:
Step-by-step explanation:
This equation represents the relationship between the exponential functions y = e^x and y = (10^(x-1)). These two functions are equal to each other for all values of x. This can be shown by taking the natural logarithm of both sides of the equation, which gives us:
ln(e^x) = x-1
In this equation, ln(e^x) is equal to x, since the natural logarithm of an exponential expression with a base of e is the exponent. Therefore, we can simplify the equation by taking the natural logarithm of both sides:
ln(10^(x-1)) = x-1
e^(x-1) = 10^x
The two functions e^x and 10^(x-1) are the same function with different bases, so they follow the same pattern. The fact that these two functions are equal to each other for all values of x can also be shown by graphing the two functions and seeing that they overlap perfectly.
Which graph shows function f?
The graph of f(x) is the second one, so the correct option is B.
Which graph shows function f?Here we have f(x), a piecewise function, and we want to see which one of the four graphs is the correct one.
You can see that the first domain of the function is:
x ≤ -4
So we must have a closed circle at x = -4, when the parabola ends.
The second domain is:
-4 < x < 1
So x here is not equal to -4 nor 1, so this part starts and ends with open circles.
finally, the linear part starts with a closed circle.
Also, notice that the line has a negative slope, so it goes down, then we can discard the first option.
Then we can see that the correct option is the second graph.

Using the length formula we know that the length of the given arc is 30.144 miles.
What is an arc?In mathematics, an arc is a portion of the boundary of a circle or curve. It is sometimes referred to as an open curve.
The measurement around a circle that determines its edge is called the circumference, often known as the perimeter.
So, the formula to find the length of the arc is:
Length of an Arc = θ × r
Now, insert values and calculate as follows:
Length of an Arc = θ × r
Length of an Arc = 4π/5 × 12
Length of an Arc = 4π/5 × 12
Length of an Arc = 12.56/5 * 12
Length of an Arc = 2.512 * 12

The area of the triangle is 12. You subtract the way it is cut in half where the dashed line that sais (4 in.) so you take 7 - 4 = 3. Now that the 3 is left meaning it is the height of the triangle. and then the bashed line that says
(8 in.) is the base of the triangle. Multiply that and it is 24 but you have to divide by 2 which gives you 12. since there are "Identical" triangles what I do is add 12 which will give you 24 again bc of both triangles combined.
As for the rectangle is both dashed lines (4 in. And 8 in.) multiply it gives you 32, again since here is another "Identical" rectangle you add 32 + 32 = 64 (Both rectangles combined)
Lastly add 64 + 24 = 88
The side of a triangle are in the ratio 4:4:3 what kind of triangle is it (b) calculate the smallest angle of the triangle to the nearest degree
The smallest angle of the equilateral triangle is 60 degrees
If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.
To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.
For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:
Smallest angle \(= \frac{180}{3} = 60\)\) degrees.

The measure of an angle is 1°. Find the measure of the complement.
The measure of the complement of a 1-degree angle is 89 degrees.
The complement of an angle is defined as the angle that, when added to the given angle, results in a sum of 90 degrees. To find the measure of the complement of a 1-degree angle, we need to determine the angle that, when added to 1 degree, equals 90 degrees.
Let's denote the measure of the complement as x degrees. According to the definition, we can set up the equation:
1 degree + x degrees = 90 degrees.
To solve for x, we need to isolate it on one side of the equation. By subtracting 1 degree from both sides, we have:
x degrees = 90 degrees - 1 degree.
Simplifying the right side, we get:
x degrees = 89 degrees.
In summary, when an angle measures 1 degree, its complement measures 89 degrees. Complementary angles are pairs of angles that add up to 90 degrees. In this case, since the given angle measures only 1 degree, its complement is significantly larger, nearly forming a right angle. The concept of complementary angles is fundamental in geometry and can be applied to various problems involving angles and their relationships.

z = f(x, y)
x = x(u, v)
y = y(u, v)
Where
x(1, 3) = 2 and y(1, 3) = 2
To calculate zu(1,3), we make use of:
\(z_u(1,3) = f_x(x,y) * x_u(1,3) + f_y(x,y) * y_u(1,3)\)
The values x(1, 3) = 2 and y(1, 3) = 2 mean that:

ammeter to measure how quickly electrical current is flowing
through the circuit. He calculates that the current should be
0.180 amps, but he measures the current as 0.173 amps. What
is Roland's percent error?
Roland's percent error is approximately 3.889%.
This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.
The positive sign indicates that Roland's measured value is slightly lower than the actual value.
To calculate Roland's percent error, we can use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100
Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:
Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100
Simplifying the expression within the absolute value:
Percent Error = (|-0.007| / 0.180) \(\times\) 100
Since the absolute value of -0.007 is 0.007, we have:
Percent Error = (0.007 / 0.180) \(\times\) 100
Calculating the division:
Percent Error = 0.03889 \(\times\) 100
Percent Error = 3.889%.
