Use the following functions for 10–12:
f(x) = -2.5x + 12; g(x) = 21x - 28
10. Find h(x) = f(x) + g(x).
11. Find h(x) = g(x) – f(x).
12. Find h(x) = 4g(x).

Step-by-step explanation:

Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or .

10. Find h(x) = f(x) + g(x).

im alright what do you need

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
