D. y = 6x...subbing in (2,12)...x = 2 and y = 12
12 = 6(2)
12 = 12 (correct)
so (2,12) is a solution to : y = 6x
The transformation is : rotation because the two figures have the same measures
(8x - 8y + 9) - (5x - 8y - z) = 3x + z + 9
8 - 5 = 3
-8 - (-8) = 0
9 - 0 =9
0 - (-z) = z
so it is written 3x +z +9
-8a-3b+6b-5a+9b= -13a-18b
-8a-5a=-13a
3b+6b+9b=18b
Hopes that helps
Base times height divided by 2 is the area. So 14 times 22 is 308 and divided by 2 is 154 so that is your answer. I hope this helps. Could I possibly get brainliest?
