Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:

According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So





(a) $8000
V(t) = 8000

The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000

The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000

The car will be worth $1000 after 12.7 years.
The answer to the question is b
Answer:
54 units
Step-by-step explanation:
multiply 6 x 18 = 108 and divide by 2 to get 54. The equation for the area of a triangle is base x height divided by 2.
Quotient is the result of division. Assign a variable to the unknown number. Let's make it x. Write the statement as an equation.
x/5 - 10 = 3
solve for x
x/5 - 10 = 3
x/5 = 3 + 10
x/5 = 13
x = 5 × 13
x = 65
