Given the following functions f (x) and g (x), solve (f + g) (5) and select the correct answer below:

f (x) = 8x - 13

g (x) = x - 9

The addition of the function is:

(f+g) (x) = f (x) + g (x)

So, (f+g) (5) = f (5) + g (5)

To find f (5) and g (5), plug in 5 for x in both the functions.

So, f (5) = 8 (5) - 13 = 40-13 = 27

g (5) = 5-9 = - 4

Now we can add f (5) and g (5) to get the answer.

So, (f+g) (5) = 27 + (-4) = 27-4 = 23

Hence, (f+g) (5) = 23
