Question

F(x) = 2x – 5 13
g(x) = 3x – 2 26
Find f(9) +49(9)

Answer 1

Answer: -694

Explanation:

Let's assume we have to find
`f(9)+g(9)` with the given functions:

`f(x)=2x-513` (1)

`g(x)=3x-226` (2)

If we want to find
`f(9)` we have to substitute the
`x` by
`9`:

`f(9)=2(9)-513`

`f(9)=-495` (3)

If we want to find
`g(9)` we have to substitute the
`x` by
`9`:

`g(9)=3(9)-226`

`f(9)=-199` (4)

Finding
`f(9)+g(9)`:

`f(9)+g(9)=-495+(-199)`

Finally:

`f(9)+g(9)=-694`
