4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
3x-5=3x+5 There is no solution.
9x2 + 30x + 25
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
(3x + 1)(x + 5)
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
-4
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
It is equivalent to: 3x+6+5 = 3x+11
3x-5=3x+5 There is no solution.
If you mean: y-2 = 3x+2 then as a straight line equation it is y = 3x+4
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
9x2 + 30x + 25
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
-4x + 5 + 3x + 6 = -x + 11
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
(3x + 1)(x + 5)
