Solve for x first
-6x - 42 = -4x -2
-6x = -4x + 40
- 2x = 40
X = -20
The equation has one solution
We know that m o n(x) = m(n(x))
This means
(x-3) + 5 x+2
m(n(x)) = ------------- = --------
(x-3) -1 x-4
The domain of this function is all real numbers - {4}
The function with the same domain is h(x) = 11/x-4
720, because 6x5x4x3x2x1=720
Pretty sure that how you do it sorry if it’s wrong.
Hope this helps.
11)
3x = 180
x = 60
12)
6x + 18 = 180
6x = 162
x = 27
