How do I graph a parabola y=x^2-8x+15

Iwant to know what 3g+5h+4g-2h is my teacher is too selfish to tell us

What are the steps to solving the inequality 3b + 8 ≥ 14?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
