Concept Check Determine what signs on values of x and y would make each statement true. Assume that x and y are not 0. (You should be able to work these mentally.)
\frac{x³}{y} > 0
\frac{x³}{y} > 0
The quotient of two numbers is positive if they have the same sign (both positive or both negative). The sign of x³ is the same as the sign of x. Therefore, \frac{x³}{y} > 0 if x and y have the same sign.
