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>

HELP I DONT GET THIS AT ALL. ITS ABOUT INEQUALITIES EXPLANATION NEEDED
wel

Answer:

Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
