Question

You plant a spruce tree that is

is 8 inches tall that grows 6 inches a year.

ches a year and a hemlock tree that

a.write a system of linear equations that represent this situation.

b. Solve the system using any method.

Answer 1

Y = 8 + 6X is correct answer.

Explanation:

Let y be the total lenght of tree and x is number of years that has past after tree plantation.

So the total lenght of tree after x years can be presented with the help of equation given below.

Y = 8 + 6X

* This equation show that there is direct relationshop between number of years and total height of tree.

For example after 3 years the height of three will be

Y = 8 + 6(3) = 26 inches
