Question

Suppose you are determining the growth rate of two species of plants. Species A ls 25 cm tall and grows 3 cm per month. Species

B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(m) as a function of m
months

Answer 1

Answer: Last Option

`H (m) = 25 + 3m\\H (m) = 10 + 8m`

Explanation:

The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.

If m represents the number of months elapsed then the equation for the height of the plant of species A is:

`H (m) = 25 + 3m`

For species B the initial height is 10 cm and it grows 8 cm each month

If m represents the number of months elapsed then the equation for the height of the plant of species B is:

`H (m) = 10 + 8m`

Finally, the system of equations is:

`H (m) = 25 + 3m\\H (m) = 10 + 8m`

The answer is the last option
