Answer:
![f(x)=70(1.17)^x](https://tex.z-dn.net/?f=f%28x%29%3D70%281.17%29%5Ex)
Step-by-step explanation:
x is time in years
f(x) represent the average annual salary in thousand dollars
We are given
The average annual salary of the employees of a company in the Year 2005 was $70,000
We can use exponential formula
![f(x)=a(b)^x](https://tex.z-dn.net/?f=f%28x%29%3Da%28b%29%5Ex)
Since, time starts from 2005
So, at x=0 , f(x)=70
we can use it
![70=a(b)^0](https://tex.z-dn.net/?f=70%3Da%28b%29%5E0)
![a=70](https://tex.z-dn.net/?f=a%3D70)
in 2006 the average annual salary was $82,000
So, in x=2006-2005=1
f(x)=82
we can plug it and find b
![82=70(b)^1](https://tex.z-dn.net/?f=82%3D70%28b%29%5E1)
![b=\frac{41}{35}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B41%7D%7B35%7D)
![b=1.17](https://tex.z-dn.net/?f=b%3D1.17)
now, we can plug it back
and we get
![f(x)=70(1.17)^x](https://tex.z-dn.net/?f=f%28x%29%3D70%281.17%29%5Ex)
Answer:
56 adults and 35 children
sum the parts of the ratio 16 + 10 = 26
Divide 91 by 26 to find one part of the ratio
= 3.5 ← 1 part of the ratio
16 parts = 16 × 3.5 = 56 ← number of adults
10 parts = 10 × 3.5 = 35 ← number of children

Step-by-step explanation:
So first you do y=z and1+2=3 so 6=y=-0 is your answer :)
4(2y-9) is your answer factored completely out
