At time x=0, water begins to drip steadily out of a water tank. After 4 hours, there are 8.6 gallons of water in the tank. After 9 hours, 8.1 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
