If f(x)=x+8 and g(x)=-4x-3 find (f+g)(x)

Mathematics
1 answer:
nydimaria [60]3 years ago
7 0

Answer:

for this case we have the following functions:

f (x) = x + 8

g (x) = -4x - 3

Subtracting the functions we have:

(f - g) (x) = f (x) - g (x)

(f - g) (x) = (x + 8) - (-4x - 3)

Rewriting:

(f - g) (x) = x + 8 + 4x + 3

(f - g) (x) = 5x + 11

Answer:

D. (f - g) (x) = 5x + 11

What’s the difference of -36 and 3
Elanso [62]

Here is you're answer:

Remember you're subtracting integers so remember to use KCC. (Keep, Change, Change)

  • -36 - 3 =
  • Apply KCC:
  • -36 + -3 =
  • Now solve:
  • -36 + -3 = -39
  • = -39

Therefore you're answer is "-39."

Hope this helps!
