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.

What is the equation of this graphed line?

Enter your answer in slope-intercept form in the box.

Answers

Answer:

y = 2x + 2

Step-by-step explanation:

As we know, slope intercept is: y = mx + b

m is slope and b is the y-intercept.

Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.

Y=2x+2

A local farmer started the year with 56 farm animals. At the end of the year, the farmer had 63 farm animals. What was the percent of change? (Show work)

Answers

Answer:the percentage change is 7.

Step-by-step explanation:

The percentage is 7 because 63-56=7

Answer:

The answer is a increase of 12.5%

Step-by-step explanation:

The equation to find this is new minus old divided by old times 100, so it would be 63 minus 56 divided by 56 which gives you 7 over 56 times 100. 7 over 56 times 100 equals 12.5 so 12.5% is the answer

Mrs. Stephan took her children to pick out pumpkins. Cater picked out a pumpkin priced $20, and Isabel picked out a pumpkin priced $13. How much did Mrs. Stephan pay for both pumpkins, including 7% sales tax?

Answers

Answer:

$35.31

Step-by-step explanation:

(20+13) x (1+0.07) = 35.31

You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31

Step-by-step explanation:

27 divided by 9 equals 3 and the ^2 is 3x3 Which equals 9 and then the negative comes

Answer:

-9

Step-by-step explanation:

In this, you should use PEMDAS, parentheses, exponents, multiplication, division, addition, subtraction. It is the order of solving any equation. The first thing you should start with is the parentheses. -27/9 is -3. Since exponents come next, you would do -3 x -3, which equals 9. After that, all that is left is a negative sign being multiplied to 9 (which is in the parentheses still. The negative sign times 9 equals -9. Therefore, your answer is -9.
