Answer:

r= -189

Step-by-step explanation:

You subract the 8 both sides:   -13= r/9+8

Which equals to: -21= r/9

In order to get the 9 off, you have to cancel it by multiplying ( opposite of   is multiplying) both sides:

9(-21)= r

And the final answer is:  r= -189

You can check it by plugging in -189 to r and it works:)

nlexa [21]
Given that the population can be modeled by P=22000+125t, to get the number of years after which the population will be 26000, we proceed as follows:
P=26000
substituting this in the model we get:
26000=22000+125t
solving for t we get:
t=4000/125
t=32
therefore t=32 years
This means it will take 32 years for the population to be 32 years. Thus the year in the year 2032
