Consider the inequality -20.2 > 0y. Which of the following must be true? Check all that apply. 1.You cannot divide by zero.
2.The inequality is equivalent to -20.2 > 0, which is false.
3.The solution is y > 0.
4.The solution is 0 > y.
5.The solution is y = 0.

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?
