Answer:

(-1,-8)

Step-by-step explanation:

8x + y=-16

-3x + y=-5

Multiply the second equation by -1

3x - y=5

Add this to the first equation

8x + y=-16

3x - y=5

---------------------

11x    = -11

Divide each side by 11

11x/11 = -11/11

x = -1

Now we need to find y

-3x +y = -5

-3(-1) +y = -5

3+y = -5

Subtract 3 from each side

3-3+y = -5-3

y = -8

1. Over 3 years, how much more does $3000 in a savings account with an APR of 3.2% compounded
Sedbober [7]

Answer:

$1080

Step-by-step explanation:

((3000 \times 0.032) \times 2) \times 3 = 576

convert % to decimal by multiplying 3.2%x100=0.032

then multiply by initial amount 3000x0.032

then multiply by 2 because it's compounding semiannual

then multiply by 3 because it's over a 3 yr period

do the same for the quarterly compound but multiply by 4 because it's quarterly

((3000 \times 0.03) \times 2) \times3 = 1080

over a 3 yr period the quarterly compounded amount will earn:

1080 - 576 = 504

$504 more than the account compounded semiannual
