Question 1203729: Suppose that from 2020 to 2060, the number of females in the U.S. under the age of 18, in millions, can be modeled by
N = 0.150x + 38.4
Where x is the number of years after 2020.
(a) Viewing N as a function of x, what is the slope m of the graph of this function?
(b) What does the model predict the population of females under 18 (in millions) will be in 2040?

You can put this solution on YOUR website!
(a)
Read the slope directly from the function. It is written in slope intercept form!

(b)
x=20. Make the substitution and evaluate!

Suppose that from 2020 to 2060, the number of females in the U.S. under the age of 18, in millions, can be modeled by
N+=+0.150x+%2B+38.4
Where x is the number of years after 2020.
(a) Viewing N as a function of x, what is the slope+m of the graph of this function?
the slope+m=+0.150
(b) What does the model predict the population of females under 18 (in millions) will be in 2040?
x+is+the+number+of+years+after+%7B%7B%7B2020, in 2040 we havex=20
N+=+0.150%2A20+%2B+38.4
N+=+41.4
