Answer:

Step-by-step explanation:
(Given)
(Given)
(Corresponding angles)


(By exterior angle theorem)


Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
Answer:
63 books per capita in the library
<em></em>
Step-by-step explanation:
Given


Required
Determine the book per capita
To do this, we simply divide the number of books by number of person;





(Approximated)
Hence;
<em>There are 63 books per capita in the library</em>
