You are going to the mall and have $20 total to spend. You plan to buy earrings, x, and phone cases, y. Write an equation to represent how many of each item you can buy if earrings are $2
dollars each and phone cases are $4 dollars each.

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

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?
