B and D are the correct choices
7y +8= 9+3y+2y
Combine like terms.
7y+8= 9+5y
Subtract 5y on both sides.
2y+8=9
Subtract 8 on both sides.
2y=1
Your answer is 2y=1
I hope this helps!

Answer:
D
Step-by-step explanation:
We assume the rotation R is <em>counterclockwise</em> 60°.
__
The exponent on R is the number of times it is applied. That is, R² = R(R(figure)). So, the composition is equivalent to R^(2-4) = R^-2.
When the exponent of R is negative, it is essentially the inverse function. That is, applying the function R to the result will give the figure you started with. Equivalently, it is rotation in the other direction.

The point 120° clockwise from B is D.
The desired image point is D.
