Suppose you are determining the growth rate of two species of plants. species a is 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 months m. h(m ) = 25 + 3m h(m ) = 8 + 10m h(m ) = 2 + 8m h(m ) = 25 + 10m h(m ) = 3 + 25m h(m ) = 8 + 10m h(m ) = 25 + 3m h(m ) = 10 + 8m

Here we are assuming a constant growth of the plant, so we can think it as an linear relationship of the form H = a*m + b

where a is the amount of cm that the plant grows every month, m is the number of months, and b is the initial height of the plant.

then for the first plant we got: the initial height is 25 cm, and it grows 3 cm per month, then Ha(m) = 3cm*m + 25cm

For the second plant, the initial height is 10 cm, and grows 8 cm per month, then his equation is Hb(m) = 8cm*m + 10cm

Then the correct answer is the fourth option.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
