Determine which ordered pair is a solution of y=-5x-1 a. (9, –2) b. (5, 24) c. (–1, 6) d. (–4, 19)

(x, y)

y = -5x - 1

a. (9, -2) → x = 9, y = -2

-2 = -5(9) - 1

-2 = -46 FALSE

b. (5, 24) → x = 5, y = 24

24 = -5(5) - 1

24 = -26 FALSE

c. (-1, 6) → x = -1, y = 6

6 = -5(-1) - 1

6 = 4 FALSE

d. (-4, 19) → x = -4, y = 19

19 = -5(-4) - 1

19 = 19 TRUE

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
