Doreen Short was looking over the repayment schedule for a loan of $40,000.00 at 9% for 4 years with a monthly payment of $995.40. Find the final payment and amount saved if :

A.) The loan is paid off with payment 30 with a previous balance of $17,565.74

B.) The loan is paid off with payment 36 with a loan balance of $12,285.66

C.) The loan is paid off with payment 48 with a previous balance of $988.09

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

it is 10.6 according to my calculations
