We call such pairs of numbers ordered pairs, and we refer to the first and Order in which the first number refers to time and the second number refers toĭistance, we can abbreviate the above solutions as (1, 40), (2, 80), (3, 120), and If we agree to refer to the paired numbers in a specified The pair of numbers 1 and 40, considered together, is called a solution of theĮquation d = 40r because when we substitute 1 for t and 40 for d in the equation, The equation d = 40f pairs a distance d for each time t. In this chapter, we will deal with tabular and graphical representations. We have already used word sentences and equations to describe such relationships 4.Ě graph showing the relationship between time and distance.The distance traveled in miles is equal to forty times the number of hours traveled. In a certain length of time by a car moving at a constant speed of 40 miles per hour.

Students struggling with all kinds of algebra problems find out that our software is a life-saver. I think it is great! I have showed the program to a couple of classmates during a study group and they loved it. Most other programs just give you the answer, which did not help me when it come to test time, Algebrator helped me through each problem step by step. Then I got Algebrator, and it helped me not only with quadratic but also with pretty much any equation or expression I could think of! Samantha Jordan, NVĪfter spending countless hours trying to understand my homework night after night, I found Algebrator. Quadratic equations were really giving me a hard time.
