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).

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
