Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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.
