jimmy is writting a paper for one of his classes. The paper has to be 1,500 words long and so far he has written 387 words. if he only has 3 more days to write his paper and wants to write the same number of words each day, then how many words must he write per day to finish the paper?

He must write 371 words-per-day.

Step-by-step explanation:

1,500 - 387 = 1,113

1,113 divided by 3 = 371

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
