Given the equation y = 4 + 2x find the values for y given the value x If x = 3 then y=
If x = -7 then y=
If x = 1 then y=
If x= -3 then y=

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?
