250–(542÷410+42) = 250–(516÷410+42) Step 1 = 250–(80÷410+42) Step 2 = 250–(80÷40+42) Step 3 = 250–(2+42) Step 4 = 250–44 Step 5 = 206 Step 6

y -5 = (-1/4)(x + 8)

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

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)
