Solve the following system of equations.

x − 2y = 5
−3x + 2y = 7

a. x = 3, y = 1
b. x = −6,
c. x = 3, y = −1
d. x = 11,

about 0.75 hours

step-by-step explanation:

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)
