ANSWER: Yes, each product is 16.
Assume that y varies inversely as x. Write an inverse variation equation that relates x and y.
2. y = 5 when x = 10
ANSWER: 3. y = −2 when x = 12
ANSWER: Solve. Assume that y varies inversely as x.
4. If y = 6 when x = 3, find x when y = 5.
5. If y = 3 when x = 2, find y when x = 4.
