3. Carl earned 8 x + 7 dollars this week mowing yards while Patrick earned -3 x + 18 dollars
walking dogs. Which of the following shows
how much the boys earned all together and
also how much more Carl earned this week
than Patrick earned?
5 x + 25 and 11 x + 25
5x + 25 and 11 x-11
5x + 11 and 5 x + 25
5 x + 25 and 5 x-11

Step-by-step explanation:

5 x + 25 and 11 x + 25

5x + 25 and 11 x-11

5x + 11 and 5 x + 25

5 x + 25 and 5 x-11 this all equal to 5,900 dived by 5

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
