Jacob has 8 times as many cookies as elisabeth. if jacob gives elisabeth 20 cookies, she will have twice as many cookies as jacob. how many cookies does each of them have?

  Jacob starts with 32 cookies; Elisabeth starts with 4.

Step-by-step explanation:

Let x represent the number of cookies Elisabeth starts with. Then Jacob starts with 8x. After the transfer of cookies, we have the relationship ...

  2(8x -20) = (x +20) . . . . Elisabeth will have twice the number of cookies Jacob has

  16x -40 = x + 20 . . . . . . simplify

  15x = 60 . . . . . . . . . . . . add 40-x

  x = 4 . . . . . . . . . . . . . . . divide by 15

Elisabeth starts with 4 cookies; Jacob starts with 32 cookies.

After Jacob gives Elisabeth 20 cookies, he has 12 and she has 24, twice his number.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
