Mitchell read a total of 24 books over 8 months. if mitchell has read 45 books so far, how many months has he been with his book club? assume the relationship is directly proportional.

15 months

Step-by-step explanation:

24/8 = 45/x

24x=45×8

24x=360

x=360/24=15

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
