F + 2/9 = 9 * 9 + 1/9
f + 2/9 = 81 + 1/9
f + 2/9 = 82/9
f = 82/9 - 2/9
f = 80/9

Since the answer choices seem to be mixed fractions, lets make 80/9 into one of them to get our answer.

9 divided by 80
9 divided by 80 is 8 with a remainder of 8
Now lets make it a mixed fraction

F(x)=|3x+5|+6<br> g(x)=7<br> find (f+g) (x).

horrorfan [7]

Answer:

$(f+g) (x)=\mid 3x+5\mid+13$

Step-by-step explanation:

<u>Operation of Functions</u>

Given:

$f(x)=\mid 3x+5\mid+6$

$g(x)=7$

The sum of (f+g) (x) is:

$(f+g) (x)=\mid 3x+5\mid+6+7$

We cannot operate with the expression inside the absolute bars, thus:

$\boxed{(f+g) (x)=\mid 3x+5\mid+13}$
