so start with y = -x^2 + 5x + 7 then complete the square: = -(x^2 -5x -7) = -(x^2 -5x + 4/25 - 7 -4/25) = -( (x-2/5)(x-2/5) -7 -4/25) = -(x-2/5)^2 -(7 4/25)

20x+7=5x+10 15x=3 3/15=.2 x=.2

9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7

2x + 5x + 25 = 17x + 25 = 1Subtract 25 from each side of the equation:7x = -24Divide each side by 7:x = -24/7That's the only answer there is.

y=5x+2 if y equals -4
