7x2 -4x -5x2 +2x = 2x2 -2x

4x+2y-8=0 2y=8-4x y=4-2x slope= -2

2x + 2 = 4x -1 2x = 3 x = 1.5

2x-3=4x+9 -2x-12=0 2x=-12 x=-6

y = (4x+9)/(2x+3)2xy+3y = 4x+93y-9 = 4x-2xy3y-9 = x(2-2y)x = (3y-9)/(2-2y)So, inverse function is 3x minus 9 divided by 2 minus 27.

7x2 -4x -5x2 +2x = 2x2 -2x

-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3

(2x-1)(2x-1) = 4x^2 -4x + 1

4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3

7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6

4x - 5 + 2x = 37
