An airplane takes off, climbs 3,000 ft, and then descends 600 ft. What is the airplane's current height? what's the numerical expression ?

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)

step-by-step explanation:

your answer is a

a. positive: 2 or 0; negative : 2 or 0; complex: 4or2or0
