Answer:
f(g(x)) = 9x^2 + 15x - 6
Step-by-step explanation:
We are using function g(x) = 3x - 1 as the input to function f(x) = x^2 + 7x.
Starting with f(x) = x^2 + 7x, substitute g(x) for x on the left side and likewise substitute x^2 + 7x for each x on the right side. We obtain:
f(g(x)) = (3x - 1)^2 + 7(3x - 1).
If we multiply this out, we get:
f(g(x)) = 9x^2 - 6x + 1 + 21x - 7, or
f(g(x)) = 9x^2 + 15x - 6
Answer:
The projected population in 2026 is of 699.3 million.
Step-by-step explanation:
Population:
The population, in x years after 2000, is given by the follwing equation:

That is:

What is projected population in 2026?
2026 - 2000 = 26, so this is y(26).

The projected population in 2026 is of 699.3 million.
Answer: I think it helps with the square units that both squares have.
Step-by-step explanation:
A is the right answer ( I say) because 1 over 4 if you times it with 2 you get 1 over 8
Your welcome I hope this works for u
