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.

To answer the question above, know that one of the way of writing the equation of the line is through the point - slope form which is generally expressed as,
y - y1 = m(x - x1)
where m is the slope and x1 and y1 are the abscissa and ordinate of the point, respectively.
Substituting the given data to the equation above,
y - 5 = -1(x -0)
By simplification we get an answer of
y = -x + 5
Answer:
30
Step-by-step explanation:
y/x = 30/(x + 10)
(y + 12)/x = 54/(x + 10)
y/x + 12/x = 54/(x + 10)
30/(x + 10) + 12/x = 54/(x + 10)
30x + 12(x + 10) = 54x
30x + 12x + 120 = 54x
120 = 12x
x = 10
EG = x + x + 10
EG = 10 + 10 + 10
EG = 30
