Start with f(x) = (x-9)/(x+5) and g(x) = (-5x-9)/(x-1). To obtain f(g(x)), throw out each appearance of x in f(x) = (x-9)/(x+5) and replace it with <span>g(x) = (-5x-9)/(x-1):
f(g(x)) = [</span>(-5x-9)/(x-1) - 9] / [<span>(-5x-9)/(x-1) + 5]
Now simplify the algebra. If your result equals just x, then you have proven that f and g are inverses of one another. Need help with the fractions? If so, do what you can and share it here; I'd then be glad to give you feedback on your work.</span>
The middle 3 are appropriate because the other two they are two young to do

Answer:
the value of output is 29
Step-by-step explanation:
the output variable y is 12 less then the input variable x.
Input variable is x, output variable is y
output values = input variable - 12
now plug in the variable in the equation
output values = input variable - 12
Given the input value is 41
Substitute 41 for x
the value of output is 29
The answer is 1.72 and it would be 2 if u estimated
