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

wouldnt it be a?

Answer 2

@jim_thompson5910 please help?

Answer 3

a

Answer 4

is correct

Answer 5

are you sure?

Answer 6

yes

Answer 7

i had the qustion before

Answer 8

`Species A is 12 cm tall and grows 2 cm per month. `

we start at 12
add 2 cm each month

so we have 12 + 2m where m is the number of months

Answer 9

ok

Answer 10

`Species B is 10 cm tall and grows 3 cm per month`

similar to species A, we have 10+3m

Answer 11

told you

Answer 12

H(m ) = 3 + 10m is not correct because this says `start at 3 and increase by 10 each month`

Answer 13

thats what i thought

Answer 14

but the same if it were 2+10..

Answer 15

so it is c

Answer 16

(c) has

\[H(m ) = 12 + 2m\]\[
H(m ) = 10 + 3m\]

The first equation has a \(y\)-intercept of \(12\) and a slope of \(2\), so it represents a plant with height \(12\) at \(t=0\) and growth of \(2\) per unit of \(t\).

The second equation has a \(y\)-intercept of \(10\) and a slope of \(3\), so it represents a plant with height \(10\) at \(t=0\) and a growth of \(3\) per unit of \(t\).

These match how the growth of species A and B is described.
