If the function f(x)= -1/2x - 7 were graphed, which of the following would be true?

D.

As the x-values increase, the y-values would decrease.

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)

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
