•Inverse Variation 5-8: Solve. Assume y varies inversely as x.
5. y = 9 when x= 6. Find y when x= 2.
6. y = 4 when x = 6. Find y when x = 12.
7-8: SOLVE
7. It takes 4 hours for 9 cooks to prepare a school lunch. How long would it take 8 cooks to prepare the
lunch? (This is an inverse variation. t = time, c = cooks)
8. The current (1) in an electrical conductor varies inversely as the resistance (r) of the conductor. The
current is 2 amperes when the resistance is 960 ohms. What is the current when the resistance is 480 ohms?
