What is the answer of 2/3+12a

-1/4

Step-by-step explanation:

2/3+12a=0

3+12a=3×0

3+12a=0

12a=-3

a=-3/12

a=-1/4

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)
