30 Which set of ordered pairs contains only points that are on the graph of the function y = 24 – 3x? A {(-3,33), (0, 24), (5,9)} B {(2,18),(5,9), (9,3)} C {(1,21), (3, 18),(5,9)} D {(-3,33), (24,0), (5,9)}​

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?
