Jackson read a total of 20 books over 4 months. After belonging to the book club for 5 months, how many books will Jackson have read in all? Assume the relationship is directly proportional.

25

Step-by-step explanation:

20/4=5 so 5 books per month then a total of 5 months so 5x5=25

20 divided by 4 is 5 meaning Jackson read 5 books every month so if he read 20 books in 4 months + 5 more months he read a total of 45 books...

5*5=25

25+20=45

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
