<u>Answer:</u>
19.15
<u>Step-by-step explanation:</u>
16.80 x 5% = 0.84
16.80 - 0.84 = 15.96
15.96 x 20% = 3.19
15.96 + 3.19 = 19.15
Answer:
g(x) = ![\frac{1}{3}(x - 1) = \frac{x}{3} - \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%28x%20-%201%29%20%3D%20%5Cfrac%7Bx%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
f(x) = 3x + 5
f[g(x)] = 3[g(x)] + 5
⇒ 3[g(x)] + 5 = x + 4
⇒ 3[g(x)] = x + 4 - 5
⇒ 3[g(x)] = x - 1
⇒ g(x) = ![\frac{1}{3}(x - 1) = \frac{x}{3} - \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%28x%20-%201%29%20%3D%20%5Cfrac%7Bx%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B3%7D)
Divide both by 18.
