The population is increasing at the rate of 220
Explanation:
Given that the population of Hannah's town is increased from 1500 to 2600 in five years.
This can be written in expression as
and
![f(5)=2600](https://tex.z-dn.net/?f=f%285%29%3D2600)
We need to determine the rate of change of population.
The rate of change can be determined using the formula,
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
where
and ![b=5](https://tex.z-dn.net/?f=b%3D5)
Substituting the values in the formula, we have,
![\frac{2600-1500}{5-0}](https://tex.z-dn.net/?f=%5Cfrac%7B2600-1500%7D%7B5-0%7D)
Simplifying, we have,
![\frac{1100}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%7D%7B5%7D)
Dividing, we get,
220
Thus, the population is increasing at the rate of 220

Answer:
2706.08
Step-by-step explanation:
X=-9
subtract 6x from both sides to get x alone as -1x, subtract 2 from both sides to balance. -1x=9, or 1x=-9
