alison, beatrice and chole each had some books. alison gave beatrice and chole some books that doubled the number of books they had, lastly chole gave alison and beatrice some books that doubled the number of books they had. each of them had 32 books at the end.

<h3>What is Working backward?</h3>

Working backward is process in which calculation done in reverse direction.

let alison, beatrice and chole has x,y and z books initially,

alison gave beatrice and chole some books that doubled the number of books they had
alison, beatrice and chole has (96-2y-2z), (2y) , (2z)
chole gave alison and beatrice some books that doubled the number of books they had. each of them had 32 books at the end.

alison, beatrice and chole has 2(96-2y-2z), 2(2y) , (96-2(96-2y-2z)-4y)

at the end,
beatrice = 32

4y=32

y = 8

chole =32

96-2(96-2y-2z)-4y)=32
z=32

alison = 96-y-z

x=96-8-32
x=56

Thus the required alison, beatrice and chole each of them have at first 56, 8, 32 books.

You have two exponential functions. One has the formula h(x) = 2 x + 3. The other function, g(x), has the graph shown below.
Alex17521 [72]
To answer, we substitute each of the numbers in parentheses to x of h(x) and get the value of g(x).

A. h(2) = 2(2) + 3 = 7  ;   g(2) < 4               (neither is equal to 7)

B. h(7) = 2(7) + 3 = 17;    g(7) is not shown in the graph          (not true)

C. h(2) = 7   ; g(2) < 4   Thus, g(2) < h(2)   (choice is not true)

D. From C, g(2) < h(2)   (TRUE)

Thus, the answer to this item is letter D.
