2-9 + 10

bored how many points do u have?

3

Step-by-step explanation:

2 - 9 + 10

-7 + 10

3

2 - 9 + 10 = 3 and i have exactly 111 points

the answer is 99.

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)
