Answer: A. f(g(x)) =x and g(f(x))=x and f and g are inverses.
Step-by-step explanation:
A function <em>g</em> is the inverse of function <em>f</em> if
<em>f(g(x)) = g(f(x))=x</em>
Given: f(x)= x+4 , g(x) = x-4
f(g(x)) = f(x+4) = (x-4)+4
= x-4+4 = x
i.e. f(g(x)) =x
g(f(x))= g(x-4) = (x-4)+4 =x
i.e. g(f(x))=x
Hence, f(g(x)) =x and g(f(x))=x and f and g are inverses.

Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
5(y-2) = 35 (divide both sides by 5)
(y-2) = 35/5
y-2 = 7 (add 2 to both sides)
y = 7 + 2
y = 9
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.
3x/5+25y=10, multiply all terms by 5 and the denominator cancels out
3x+125y=50, subtract 3x from each side
125y=-3x+50, divide both sides by 125
y=(-3+50)/125
slope=m=-3/125
y intercept=b=2/5
