Answer! what is the value of x/2 +3x-y ? (x/2 is a faction btw) when x=8 and y=2 a) -12 b) -6 c) 26 d)30

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?
