2. The product of x + 3 - 1 is less than 12.
3. The product of two integers is 64 and their difference is 12. Find the two integers.

III. Solve each problem. Show your solution.
1. If y varies directly as x, and y = 8 when x = 4, find y when x= 3.
2. If r varies directly as the cube of s, and r =8 when s = 2, Find r when’s = 5.
3. If y varies inversely as x, and y = 24 when x = 8, find x when y = 10.
4. Y varies inversely (x -3). If y = 5 when x = 7, find y when x =5.
