Write the absolute value equations in the form x−b =c (where b is a number and c can be either number or an expression) that have the following solution sets: All numbers such that x≥15.

What are the sotions to the quadratic equation 9x^2=4

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

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4
