What value of y makes the expression equal to a value that is less than 7?

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

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.
