ABC transforms to produce A’ B’C’ which transformation did NOT take place. A. Rotation 180° counterclockwise about the origin B. Reflection across the origin
C. Rotation 180 clockwise about the origin
D. Reflection across the Line y=x

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
