While riding her bike to the ocean and back home 66 times, Christine timed herself at 65min65 min, 53min53 min, 56min56 min, 50min50 min, 63min63 min, and 56min56 min. She had set a goal of averaging 5757 minutes for her rides. How many minutes will she need to spend on her seventh ride to attain her goal?

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)

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation

once you solve it out the value of x is 13
