The general equation for depreciation is given by y=a(1-r)^t where y=current value.
Jlenok [28]

With the help of the given equation, we know that the automobile is worth $12528.15 after four years.

<h3>What are equations?</h3>
  • A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
  • a formula that expresses the connection between two expressions on each side of a sign.
  • Typically, it has a single variable and an equal sign.
  • Like this: 2x - 4 Equals 2.
  • In the above example, the variable x exists.

So, the equation of depreciation: y = A(1 - r)∧t

The current value is y.

A is the initial cost.

r is the depreciation rate.

t is the time in years, and

In four years, we must ascertain the present value.

Now,

y = $24000(1 - 0.15)⁴

y = 24000(0.85)⁴

y = 24000 × 0.52200625

y = 12528.15

Therefore, with the help of the given equation, we know that the automobile is worth $12528.15 after four years.

Complete question:
The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $

Nezavi [6.7K]

Answer:

x = 2

Step-by-step explanation:

x + 5 = 2x + 3 ( subtract x from both sides )

5 = x + 3 ( subtract 3 from both sides )

2 = x

Graph: y &lt; 1/3x + 1/2
fiasKO [112]

Answer: See attached.

Step-by-step explanation:

         Since this inequality uses < and not ≤, we will be using a dashed line.

         Next, we will shade "below" the line since this inequality uses the < aka less than.

         Lastly, our y-intercept is \frac{1}{2}.
