Answer:

Step-by-step explanation:
We have the equation
.
The ordered pairs of this equation have the form 
Where x is the independent variable and y is the dependent variabe.
That is, the points belonging to the line
have the form 
For
.
So, we need to find
for x_0 = -3.
Then we substitute x = -3 into the equation and clear the value of y.

.
Then the ordered pair is:

To find the percent of increase take the difference of the two divided by the original. (62-55)/55 = .12727272727. So 13% if they want you to round to the nearest percent.
To set up your system of equations is to have 2 equations. They both would have 1 similar variable. For example, Jenny is 5 more her brother's age. She is also 2 more than twice her brother's age. You would set this up as Y, which is Jenny, and X, her brother. Y = 5 + x and Y = 2x + 2. Make sure you put Y in the same spot in both equations. Then take the other half of the equations and simplify them. 5 + x = 2x + 2. Subtract x from both sides to get 5 = x + 2. Subtract 2 from both sides to get 3 = x. Now replace the X from both equations to get Y = 5+3, and Y = 2(3) + 2. You will see both add up to 8, which is how old Jenny is in this example. Hope this helped!
4ft divided by 2/3ft
4/1 divided by 2/3
4/1 times 3/2 is 12/2 or 6 pieces, 0 remaining.
I think the answer is:
30,000+200s = 80,000
where s represents the sales
