The left and right page numbers of an open book are two consecutive integers whose sum is 45. find these page numbers.
the smaller page number is
the larger page number is

The smaller page number = 22

 The larger page number = 23

Step-by-step explanation:

Let the smaller page be x

The larger page number  = x +1

    x + ( x+1 ) = 45

         2x + 1 = 45

              2x = 45- 1 = 44

               x = 44/2 = 22

The smaller page number = 22

 The larger page number = 23

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
