7(x+3)=9 is the formula
Distribute the 7

7x=-12
Divide 7 on both sides
X=-12/7
Answer:
The value of the car would be $400 at the start of 2017.
Step-by-step explanation:
At the start of 2014 Mike's car was worth = $12,000
The value of the car decreased by 30% every year.
We have to figure out the value of the car after 3 years at the start of 2017.
=
= 12000 × 0.3
= $4000
_______________________________________________
4000 x 0.3 = 1200.
_______________________________________________
1200 x 0.3 = 400
So the value of the car would be $400 at the start of 2017.
Yes function because each x has only one value
