Triangles DEF and D'E'F' are shown on the coordinate plane below:
Lorico [155]

The <em><u>correct answer</u></em> is:

90° clockwise

Explanation:

Comparing the image points to the pre-image points, we can see that in every ordered pair, x and y have been switched and x has been negated.  Algebraically, this means (x, y)→(y, -x).

This is the same mapping that a 90° clockwise rotation performs, so that is our answer.

M(4, 2) is the midpoint of RS. The coordinate of S are (6, 1). What are the coordinates of R?
Juliette [100K]

Answer:

Step-by-step explanation:

Compare coordinates of S and M

difference in x-coordinates = 4-6 = -2

difference in y-coordinates = 2-1 = 1

x-coordinate of R = x-coordinate of M - 2 = 4-2 = 2

y-coordinate of R = y-coordinate of M + 1 = 3

Herbert has sold 99, 37, 86, and 73 copeirs in the last 4 months, respectivly. How many copiers will he need to sell this month
jolli1 [7]

Answer:

Therefore 80 ceperies will he need to sell this month.

Step-by-step explanation:

Average: Average is the ratio of sum of all numbers to the total number present in the data.

Given that Herbert has sold 99, 37, 86 and 73 copeirs in the last 4 months.

Let he need to sell x copeirs in this month.

According to the problem,

\frac{99+37+86+73+x}{5}=75

⇒ 99+37+86+73+x= 75×5

⇒295 + x= 375

⇒x = 375 - 295

⇒ x= 80

Therefore 80 ceperies will he need to sell this month.
