f(x)=(x+4) ^2 −25

to solve set equal to zero

0 =(x+4) ^2 −25

add 25 to each side

25 = (x+4) ^2

take the square root of each side

square root (25) =(x+4)

+- 5 = (x+4)

5 = x+4      -5 = x+4

subtract 4 from each side

1 =x            -9 =x

The population of a town is decreasing at a rate of 3.2% per year. In 2015, there were 14,250 people. What is the first year tha
notsponge [240]
The answer is D
you would set up an equation like this
14,250 x .032
this will give you how much the population is decreasing per year. Which is 456 people per year.
You then take 2015 and find the difference between that number and 2025 and do it with all of the other years too.
For example 2025-2015 is 10 years
You then take 10 x 456 to tell you how much the of population you lost in those 10 years. You will then take that number which is 4,560 and do 14,250-4,560 to get 9,650.
