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 m months. h(m) = 12 + 2m h(m) = 10 + 3m h(m) = 2 + 12m h(m) = 3 + 10m h(m) = 12 + 2m h(m) = 3 + 10m h(m) = 2 + 12m h(m) = 10 + 3m
