X²- 7x + 10 = 0 find the sum and product of the roots of each quadratic equations

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

Iam at home. /: i am playing video games. translate the following statement into symbolic form.

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
