Answers

Answer:

y = 4x + (-9)

Step-by-step explanation:

You can observe that the line crosses the y-axis at -9, so that is our y-intercept.

For the slope, just take the y-intercept for example, and count how many squares the line goes up before reaching 1. In this problem you can see that the line goes 4 squares up in the time it takes to go 1 square to the right, so the slope is y over x, meaning 4 over 1, or just 4.

Answer:

The answer should be y = 4x + (-9).

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?

Answers

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.

Line segment EF is shown on a coordinate grid:

A coordinate plane is shown. Line segment EF has endpoints negative 3 comma 2 and negative 1 comma 2.

The line segment is rotated 180 degrees counterclockwise about the origin to form E′F′. Which statement describes E′F?

Group of answer choices

E′F′ is perpendicular to EF.

E′F′ and EF are equal in length.

E′F′ is half the length of EF.

E′F′ is greater than twice the length of EF.

Answers

Answer:

E'F' and EF are equal in length.

Step-by-step explanation:

This is because it is a mirror translation over the y-axis, and the length is not changed.

If you rotate a line 180° it’ll be the same line but the endpoints will be swapped because you’re just flipping it over. This means they are the same in length, while they’re in the same position essentially, this is the only answer that fits because it’s not perpendicular, E‘ F‘ is not half the length of EF,And it’s not greater than twice the length either. This means your answer is answered number two, E’F’ and EF are the same length.
