Question

Pleaseeee help meeee

Answer 1

Ответ:

See explanation

Пошаговое объяснение:

a) V = 16 - 1,6 t,

where V - value, thousands of dollars;

t - time, years.

b) After 4,5 years time is 4,5, thats why:

V₄,₅ = 16 - 1,6 · 4,5 = 16 - 7,2 = 8,8 thousands of dollars.

Answer 2

Answer:

a. The equation for the depreciated value is: v = 16 – 1.6t.

b. The value of the car after 4.5 years would be $8,800.

Step by step explanation:

a. The linear equation should be of the form: v = kt + b

Values v₀ = 16 and t₀ = 10 are the intercepts, thus equation can be written as:

v / v₀ + t / t₀ = 1

v / 16 + t / 10 = 1

5v + 8t = 80

v = 16 – 1.6t

NB: the same result can be obtained by simultaneously solving the following equations for k and b:

{ 16 = k·0 + b

{ 0 = k·10 + b

b. The value of the car after 4.5 years would be:

v = 16 – 1.6 · 4.5 = 8.8 (thousands of dollars).
