Elroy enjoys roller skating and weight training. Let X represent the number of hours he spends roller skating weekly, and let Y represent the number of hours he spends weight training weekly. The mean of X is 5 hours, and the mean of Y is 7 hours. Which answer choice correctly calculates and interprets the mean of the sum, S = X + Y?

207/8 is the right

the correct answers i think are b. and d.

give me brainliest if it is correct!

answer:

c) the x-coordinate of the center of the circle increases by 3

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
