The answer is -11/2, 9/2

Explanation

You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10

Then you solve for X in each equation.
2x+1=10 would give you 9/2

2x+1=-10 would give you -11/2

So your final solutions would be x1= -11/2 x2= 9/2

cupoosta [38]

Answer:

Principal element is $475.43

Interest payment is $390

Step-by-step explanation:

The amount of interest paid in month one is 4%*$117,000*1/12=$390

The interest is calculated based on the annual interest rate of 4% apportioned to reflect one month interest by multiplying by 1/12

The principal element of monthly payment is the monthly payment minus interest.

principal paid in month one=$865.43-$390=$475.43

Ultimately,$475.43 goes toward reducing her loan balance while the $390 is interest on loan
