- h(x) = f(x) + g(x) =

- h(x) = g(x) – f(x) =

- h(x) = 4g(x) =

<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or
.
10. Find h(x) = f(x) + g(x).
⇒ 
⇒ 
⇒ 
⇒ 
11. Find h(x) = g(x) – f(x).
⇒ 
⇒ 
⇒ 
⇒ 
12. Find h(x) = 4g(x).
⇒ 
⇒ 
⇒ 
The point-slope form:

We have

Therefore
<h3>slope = -3 and the point (-2, 6)</h3>
------------
<h3>y + 2 = 2(x - 1)</h3>
2x - y = 4 <em>it's standard form Ax + By = C</em>
y = 2x - 4 <em>it's slope-intercept form y = mx + b</em>
y - x = 4 →<em> </em>x - y = -4 <em>t's standard form Ax + By = C</em>
The answer will be 29,000
