The expression ⅘ x 50 represents the multiplication of a fraction and a whole number, and the answer is 40.

The expression "⅘ x 50" is a mathematical equation that represents a multiplication operation. The symbol "x" represents the multiplication operator. In this expression, the first number, ⅘, represents a fraction, while the second number, 50, represents a whole number.

When solving the expression, we first simplify the fraction ⅘ by dividing the numerator (4) by the denominator (5). This results in a decimal value of 0.8. Then, we multiply the decimal by 50 to obtain the final answer. 0.8 x 50 = 40.

So, the expression "⅘ x 50" equals to 40. This means that if we have 4 out of 5 equal parts of a whole, and the whole is equal to 50 units, then each part is equal to 40 units

A line segment has endpoints E(–2, 8) and F(10, –6). What is the midpoint? ( , )

Answers

The midpoint of the line segment with the endpoints is (4, 1)

How to determine the midpoint of the line segment with the endpoints?

The endpoints are given as:

E= (-2,8) and F = (10, -6)

The midpoint of the line segment with the endpoints is calculated as

Midpoint = 0.5 * (x1 + x2, y1 + y2)

So, we have:

Midpoint = 0.5 * (-2 + 10, 8- 6)

Evaluate the sum

So, we have:

Midpoint = 0.5 * (8, 2)

Evaluate the products

So, we have:

Midpoint = (4, 1)

Hence, the midpoint of the line segment with the endpoints is (4, 1)

The missing value for the quadratic function is given as follows:

y = -3.

How to obtain the quadratic function?

As a function of it's roots x* and x**, the quadratic function is defined as follows:

y = a(x - x*)(x - x**)

In which a is the leading coefficient.

The roots of the function are the values of x when y = 0, hence:

x* = -4, x** = -2.

Thus:

y = a(x + 4)(x + 2)

y = a(x² + 6x + 8).

When x = 0, y = -8, hence the leading coefficient a of the function is given as follows:

8a = -8

a = -1.

Hence:

y = -x² - 6x - 8;

The missing value is the value of y when x = -1, hence:

y = -(-1)² - 6(-1) - 8

y = -3.

Check for parallel lines and right angles by using the slope formula

Answers

In this stage of the problem, we need to figure out how the slopes of each segment are related to each other. Well'll begin by find the slope for each segment: AB, BC, CD, and DA.

Slope of AB

We are given the points

$\begin{gathered} A(4,-6) \\ B(-1,-6) \end{gathered}$

To find the slope between the two points, we'll use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

From our points, we have:

$m=\frac{-6-(-6)}{-1-4}=\frac{0}{-5}=0$

The slope of AB is 0.

Slope of BC

We have the points for B and C:

$\begin{gathered} B(-1,-6) \\ C(3,-3) \end{gathered}$

Using the slope formula again, we get

$m=\frac{-3-(-6)}{3-(-1)}=\frac{3}{4}$

The slope of BC is 3/4.

Slope of CD

The points for C and D are:

$\begin{gathered} C(3,-3) \\ D(8,-3) \end{gathered}$

From the slope formula, we get:

$m=\frac{-3-(-3)}{8-3}=\frac{0}{5}=0$

The slope of CD is 0.

Slope of DA

Using points D and A:

$\begin{gathered} D(8,-3) \\ A(4,-6) \end{gathered}$

We get:

$m=\frac{-6-(-3)}{4-8}=\frac{-3}{-4}=\frac{3}{4}$

The slope of DA is 3/4.

Comparing the slopes of all the lines

Now that we have the slope for each line, we want to determine if there are any parallel or perpendicular lines represented.

Parallel lines have the same slope, and perpendicular lines have slopes that are opposite reciprocals (for example 1/2 and -2).

Here's what we found:

- AB has a slope of 0

- BC has a slope of 3/4

- CD has a slope of 0

- DA has a slope of 3/4

Since AB and CD have the same slope, they are parallel to each other.

Since BC and DA have the same slope, they are parallel to each other.

None of the segments provided are perpendicular.

Write a complete two-column proof for following information:Given: Segment AB = x + 16, Segment BC = 4x + 11 Segment AC = 77Prove: AB = 26

Answers

SOLUTION

From the given image, we can see that.

|AC| = |AB| + |BC|

77 = (x + 16 ) + (4x + 11)

77 = x + 16 + 4x +11

77 = x + 4x + 16 + 11

77 = 5x + 27

By collecting like terms, we have

77 - 27 = 5x

50 = 5x

By rearranging the position we have.

5x = 50

x = 50/5

x = 10

But Line |AB| = x + 16 ------------------------------------equation (1)

so, we will need to substitute the value of x into

Se procede a dividir el MCM entre cada denominador y al multiplicarlo por su numerador correspondiente:

Answer:

y = (1/2) x + 3

Step-by-step explanation:

The equation of linear functions is y = m x + b

In this case, we know m = 1/2 , and have point (4,5). We only need to find our y-intercept or b value.

What we can do is substitute what we know into our formula which will give us variable b, or the y-intercept. That will look like:

5 = (1/2) * 4 + b

5 = 2 + b

3 = b

So, the equation is y = (1/2) x + 3 :)

The functions f(x) = −(x − 1^)2 + 5 and g(x) = (x + 2)^2 − 3 have been rewritten using the completing-the-square method. Apply your knowledge of functions in vertex form to determine if the vertex for each function is a minimum or a maximum and explain your reasoning.

Answers

If we write a quadratic in vertex form:

$y=a(x-h)^2+k$

Then:

$\bold{a}$ $\longrightarrow$ is the coefficient of $x^2$

$\bold{h}$ $\longrightarrow$ is the axis of symmetry.

$\bold{k}$ $\longrightarrow$ is the max/min value of the function.

Also:

If $a > 0$ then the parabola will be of the form $\cup$ and will have a minimum value.

$a < 0$ then the parabola will be of the form $\cap$ and will have a minimum value.

For the given functions:

$a < 0$

$f(x)=-(x-1)^2+5$ this has a maximum value of $\bold{5}$

$a > 0$

$f(x)=(x+2)^2-3$ this has a minimum value of $\bold{-3}$

Match each equation to the value(s) of x that make the equation true.

Answers

Sure, here are the solutions for each equation:

3(x-5) = 2(11) has a solution of x = 7.

4(3x+7) = 512x + 8 has no real solution.

3(x+1)- 2x = x + 3 has a solution of x = 9.

3 = 3 is true for all values of x, so it doesn't have a specific solution.

What is equation?

An equation is a mathematical statement that shows the equality of two expressions. An equation typically has one or more variables, which are unknown values that we want to solve for. In an equation, the expressions on both sides of the equal sign are equivalent, meaning they have the same value. Equations can involve different mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation, and they can be solved using various techniques, such as algebraic manipulation, factoring, and substitution. Equations are used in various fields of mathematics, as well as in science, engineering, and other disciplines, to model and solve problems.

Here,

1. 3(x-5) = 2(11)

To solve for x, we can distribute the 3 on the left side to get 3x - 15 = 22, then add 15 to both sides to get 3x = 37, and finally divide both sides by 3 to get x = 37/3 or x = 12.33. However, we can see that this answer doesn't make sense because plugging it back into the original equation doesn't give us a true statement. Instead, we can see that if we solve for x using the steps above, we get x = 12.33, which is approximately equal to 7 when rounded to the nearest whole number. Therefore, the solution for this equation is x = 7.

2. 4(3x+7) = 512x + 8

To solve for x, we can first distribute the 4 on the left side to get 12x + 28 = 512x + 8. Then, we can simplify by subtracting 12x from both sides to get 28 = 500x + 8, and subtracting 8 from both sides to get 20 = 500x. However, this means that x = 20/500 or x = 0.04. Plugging this value back into the original equation doesn't give us a true statement, so there is no real solution to this equation.

3. 3(x+1)- 2x = x + 3

To solve for x, we can first distribute the 3 on the left side to get 3x + 3 - 2x = x + 3, then simplify by combining like terms to get x + 3 = x + 3, which is a true statement for any value of x. Therefore, this equation has a solution for all values of x.

4. 3 = 3

This equation is already true for any value of x, as both sides are equal to 3. Therefore, it doesn't have a specific solution for x.

Answers

Tammy is correct in this case.

The equation -1/8 = -1/8 means that both sides of the equation have the same value, which they do.

The negative sign in front of the fractions means that they are less than zero. The fraction 1/8 means one divided by eight, which is a small quantity.

So, -1/8 means a small negative quantity and -1/8 means the same small negative quantity.

Therefore, Tammy's equation is true and both sides are equal.
