The equation to show the depreciation at the end of x years is

f(x) = 1500 - 200x

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

This is properly written as

f(x) = 1500 - 200x

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

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

Chloe and tino have a combined age of 48. three years ago chloe was double the age tino is now. find tinos age
jeka94

As  given Chole and Tinos age , the present age of Tino is equal to 15 years.

As given,

Let x and y be the present age of Chole and Tino. respectively.

Combined age = 48

Given condition,

x + y = 48 _______(1)

Three years ago

x - 3 = 2y

⇒x =2y +3 _______(2)

Substitute the value of x in (1),

2y+3 +y =48

⇒ 3y = 45

⇒ y = 15years

Therefore , as given Chole and Tinos age , the present age of Tino is equal to 15 years.
