First, let's deal with the fraction in the denominator of the exponent. Multiply the top and bottom of the exponent by 6.

Now that the fraction in the denominator is taken care of, we can reduce the denominator.
. Some professors might accept this as simplest form, but others might ask you to get rid of the negative.

Hi!
We can see here that this is a composition question.
And since the composition of g of f of x is x, we can conclude that g(x) is the inverse of f(x) (if you're confused, search up the definition of an inverse function).
To find an inverse function, we can take the f(x) function and change the positions of the x and y variables.







Which is answer choice A, to check your work, you can solve the composition of g(f(x)), which will get you x.

Hope this helps!

I think it's 64. Not positive, but pretty sure it is.
X=20
If they're parallel the other number in the same spot as 5x+15 equals that, so 5x+15=115 because if they are parallel they're the same if same spot and same line going through them.
115-15 = 100
5x=100
Divide by 5 both sides
X=20
If x=20 then these lines would be parallel
