Draw the figure out and you will find that AB + BC = AC. Given this, put the equations together to form x+41+x+10=22. Solve to get x=-29/2

Answer:

7. $(f+g)(x) = 6x - 2$

8. $(f-g)(x) = 2x + 8$

Step-by-step explanation:

We are given two function, f(x) and g(x).

We want to find their addition and their subtraction, and we do this combining like terms.

The functions are:

$f(x) = 4x + 3$

$g(x) = 2x - 5$

7. Find (f+9) (x)

$4x + 3 + 2x - 5 = 4x + 2x + 3 - 5 = 6x - 2$

$(f+g)(x) = 6x - 2$

8. Find (f - g) (x)

$4x + 3 - (2x - 5) = 4x + 3 - 2x + 5 = 4x - 2x + 3 + 5 = 2x + 8$

$(f-g)(x) = 2x + 8$
