We are given (xy)^(-3).
This leads to 1/(xy)^3.
You see, going from the top to the bottom alters the sign of the exponent to its opposite.
ANSWER: 1/(x^3•y^3)

The correct answer for this question is that the unit rate is 5:1. We
can work this out by simplifying down the 2 commercials to every 10
songs ration, so that 10:2 becomes 5:1. We can work this out by halving
the original ratio to simplify it.
Answer:
C
Step-by-step explanation:
Given
6(x + 4) = 2(y + 5) ← distribute parenthesis on both sides of the equation
6x + 24 = 2y + 10 ( subtract 10 from both sides )
6x + 14 = 2y ( divide all terms by 2 )
3x + 7 = y, hence
y = 3x + 7 → C
