For which equations is x = 9 a possible solution? Check all that apply. O |x1 = 9
O -|x| = 9
O -|-x] = 9
O -|-x) = -9
O [x] = -9
O |-x1 = 9
O |-x) = -9

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?
