A. (f + g)(x) = f(x) + g(x) = 4x - 5 + 3x + 9 = 7x + 4
B. f.g (x) = f(x) * g(x) = (4x - 5)*(3x + 9) = 12x^2 + 36x - 15x - 45
= 12x^2 + 21x - 45
C Replace the x in f(x) by g(x):-
= 4(3x + 9) - 5
= 12x + 36 - 5
= 12x + 31
Answer:
x=7
Step-by-step explanation:
I believe we are solving for x. In that case, let us start by moving 1 to the other side.

Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:

Now, we may divide both sides by 4 to get rid of the coefficiant:

When we subtract both sides by 3, we get
x=7
