If y + 1= 2015, for what positive integer w will 2y^2 + 2y = 2015w?

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

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
