That's weird. There is no error!
X ≤ -16 is the solution I think?
40 - 8 = 32
Therefore, there are 32 boys
(32/40)*100 = 80
Therefore, percentage of boys = 80%
Answer:
- 17
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x)
f(- 2) = 4(- 2) = - 8, then
g(- 8) = 2(- 8) - 1 = - 16 - 1 = - 17
