A car was originally purchased for $30,000. The following equation gives the car's value when it has been driven a total of m thousand miles over a period of t years.

V = $30,000(0.7 + 1/m) ^t

If the car has been driven a total of 35,000 miles over a period of 6 years, what is its value?
OA.
$6,322.60
ОВ.
$9,707.36
OC. $2,748.65
OD.
$4,486.98

your answer is #3 , 8 - 3 square root of 11

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
