Four friends were building a wall. matt built 2/8 of the wall. pat completed 1/8 of the wall. lucy built 2/8 of the wall. how much of the wall did they build?

3,000,540

step-by-step explanation:

goog may have it for you

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)
