Which expression is equivalent to (x-4y/x-9y5)-2

go on the tube you might find some information there

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
