Question

Suppose you are determining the growth rate of two species of plants. Species A is 12 cm tall and grows 2 cm per month. Species B is 10 cm tall and grows 3 cm per month. Which system of equations models the height of each species H(m) as a function of months m.
H(m ) = 12 + 2m
H(m ) = 3 + 10m
H(m ) = 2 + 12m
H(m ) = 3 + 10m
H(m ) = 12 + 2m
H(m ) = 10 + 3m
H(m ) = 2 + 12m
H(m ) = 10 + 3m

Answer 1

First one has initial height of 12 cm and on that inicial height we add 2cm each month which can be written as 2m + 12

Second one has initial height of 10 cm and grows 3cm per month which can be written as 3m + 10

Now we just have to find those expressions in offered equations to find answer.

We can see that system of equations is:
H(m) = 12 + 2m
H(m) = 10 + 3m

or third pair.
