After a new $28,000 car is driven off the lot, it begins to depreciate at a rate of 18.9% annually. Which function describes the value of the car after t years?

C(t)=28,000(1.575)tcap c times t is equal to 28 comma 000 times 1 point 5 7 5 to the t th power , ,

C(t)=28,000(0.158)tcap c times t is equal to 28 comma 000 times 0 point 1 5 8 to the t th power , ,

C(t)=28,000(0.189)tcap c times t is equal to 28 comma 000 times 0 point 1 8 9 to the t th power , ,

C(t)=28,000(0.811)tcap c times t is equal to 28 comma 000 times 0 point 8 1 1 to the t th power , ,

tube or goog would be a great resource to with that question

{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
