Answer:
<em><u>=15a−8</u></em>
Step-by-step explanation:
Let's simplify step-by-step.
4(2a−1)−4+7a
Distribute:
=(4)(2a)+(4)(−1)+−4+7a
=8a+−4+−4+7a
Combine Like Terms:
=8a+−4+−4+7a
=(8a+7a)+(−4+−4)
=15a+−8
Answer:
=15a−8

Answer:
P(0) = 7,917
Step-by-step explanation:
The population of the community is given by the following formula:

In which P(0) is the initial population and r is the growth rate.
The initial population P0 has doubled in 5 years.
This means that 

Which lets us find r.



Applying the 5th root to both sides


So

Suppose it is known that the population is 12,000 after 3 years.
With this, we find P(0)
