If f(x)=|x|+9 and g(x)=-6 wich describes the value of (f+g)(x)

(f+g)(x)= |x| + 3

Step-by-step explanation:

To find (f+g)(x), you must add f(x) and g(x) together.

(f+g)(x)= |x|+9 + (-6)

Then, combine like terms.

So,  (f+g)(x)= |x| + 3

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.
