During a sale, a store offered a 15% discount on a tablet computer that originally sold for $520. After the sale, the discounted price of the tablet computer was marked up by 15%. What was the price of the tablet computer after the markup? Round to the nearest cent.

so what is the question

step-by-step explanation:

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.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

i belive those are the ones that are under 90 degreese.
