Step-by-step explanation:
range is the y value
$7881.18
Step-by-step explanation:
Let the initial Investment be
. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.
As the annual interest rate is 12%, the monthly interest rate is 1%.
Since this is a compound interest problem, the total amount can be modeled as follows: 
Here
is the interest rate, i.e
, and t is the number of time periods, i.e
= 


∴ Initial Investment = $7881.18
First you divide 439.92 by 15.6 and you get 28.2 which is how many miles per gallon that you are getting. Then you take 28.2 and multiply it by how many gallons that it says (39.7) The final answer is 1119.54
Assuming that the expression equals 0
3x+9=0
Subtract 9
3x= -9
-9/3= -3
x= -3
