The equation V = -2000t + 23,000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $15,000, substitute 15,000 into the equation to find the age of the car.

The care is 4 years old

Step-by-step explanation:

V = -2000t + 23,000

15000 = -2000t + 23,000

15000 - 23000= -2000t (+ 23,000 - 23000)

- 8000 = -2000t

- 8000/-2000 = -2000t/-2000

t = 4

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
