The only one you might use it the triangle
The equation to show the depreciation at the end of x years is
![f(x) = 1500 - 200x](https://tex.z-dn.net/?f=f%28x%29%20%3D%201500%20-%20200x)
Data;
- cost of machine = 1500
- annual depreciation value = x
<h3>Linear Equation</h3>
This is an equation written to represent a word problem into mathematical statement and this is easier to solve.
To write a linear depreciation model for this machine would be
For number of years, the cost of the machine would become
![1500 - 200x](https://tex.z-dn.net/?f=1500%20-%20200x)
This is properly written as
![f(x) = 1500 - 200x](https://tex.z-dn.net/?f=f%28x%29%20%3D%201500%20-%20200x)
where x represents the number of years.
For example, after 5 years, the value of the machine would become
![f(x) = 1500 - 200x\\f(5) = 1500 - 200(5)\\f(5) = 1500 - 1000\\f(5) = 500](https://tex.z-dn.net/?f=f%28x%29%20%3D%201500%20-%20200x%5C%5Cf%285%29%20%3D%201500%20-%20200%285%29%5C%5Cf%285%29%20%3D%201500%20-%201000%5C%5Cf%285%29%20%3D%20500)
The value of the machine would be $500 at the end of the fifth year.
From the above, the equation to show the depreciation at the end of x years is f(x) = 1500 - 200x
