Answer:
a = 1
Step-by-step explanation:
The factor in front of x must be the same in both equations.
So (a+2) in the first must be 3 (like it is in the second).
That is the case when a=1.
So the +7 and the -4 are not relevant!

Answer:
A = 236,000 (1+ 0.04)^9
335,902 people in 2009
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population (in 2000)
r = growing rate (decimal form) = 4/100 = 0.04
t= years
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04) ^t
To find the population in 2009:
We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)
Substituting t=9 in the function:
A = 236,000 (1+ 0.04)^9
A =335,902 people
