Answer:
(2001, 2125), (2006, 2360)
Step-by-step explanation:
An ordered pair refers to a pair of numbers or items in a simple and orderly manner. The order in which the items are grouped is very important. In graphs an ordered pair could be the coordinates of various points on the graph in terms of x and y, that is x and y coordinate (x,y).
From the question we are to form two ordered pair in the form (year, number of heart transplants).
to do this we simply fill out the items with their corresponding numbers where the first item is the year and second is the number of heart transplants.
in year 2001 we have (2001, 2125)
in year 2006 we have (2006, 2360)
7. For this one, we need an equation. Lets make x = the price of the computer. Since the price of the printer is 30% the price of the computer, we can make that .3x, because a number multiplied by .3 will give you 30% of your original number. So, our equation will be:

Since x is the cost of the computer, you have your answer right there. The computer costs $2,028.
8. For this one we're going to need a proportion, but first we need to find out how much of the percentage of seeds Cliff planted.
% of seeds planted per person:
Ali - 40
Ben - 45
Cliff - x
All percentages add up to 100, so we'll make an equation to figure this out:

Therefore, Cliff planted 15% of the seeds. Since Cliff planted 15% of the seeds, and he planted 87 total, 15% of our total number of seeds planted is 87. We can now make a proportion to figure out how many seedlings were planted all together.

We can now cross multiply in order to get a solvable equation:

The total number of seedlings planted was 580.
Sorry if this is confusing at all, hope I helped!
