Answer:
C
Step-by-step explanation:
To evaluate f(g(7)), substitute x = 7 into g(x), then substitute the result into f(x)
g(7) = (2 × 7) - 5 = 14 - 5 = 9, then
f(9) = 3(9)² - 4 = 243 - 4 = 239 → C
(P+T)-7 = 6. 7 less than, meaning taking away 7 from the sum of (P + T) is as much as / equal to 6
3y - 12x = 20
3y = 20 + 12x
y = (20/3) + 4x
