Fiona's parents invest $5,000 in a CD that earns 1.2% interest compounded annually. In 8 years, she decides to attend a local community college for two years that costs
approximately $5,400 total. Is there enough money available from the CD to pay for the
first two years of Fiona's college education?
F
Yes, the CD carns compound interest so the investment is more than double after
5 years.
G
No, the CD earns compound interest so the investment is charged a monthly fee
and loses money over 8 years.
Yes, the CD earns over $500 in interest over 8 years.
No, the CD earns $480 in interest over 8 years.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
