exis [7]

Answer: Last Option

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

Step-by-step 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
