Look at the relationship between a and b. a 9 14 19 24 b 12 17 22 27 which equation below describes the relationship between a and b? a. b = 21 - a b. b = 1 × a c. b = 3 + a d. b = 108 ÷ a

1- 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.2- 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 the first question?
