Two hundred years ago, as it became more and more evident that the
coultry would sever all ties with England, a large number of people who had
moved here decided to return to their former home. This migration was
large, in fact, that by July 4, 1776, it had decreased the American population
by 20%, and increased the population of the British Isles by 4%. Assuming
that no one who left America went anywhere else, what percent of the British
popustion was the American population before the migration?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

b

step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
