Some ordered pairs for t equal to 0, 1, 2, 3, 4, and 5 are With this agreement, solutions of theĮquation d - 40t are ordered pairs (t, d) whose components satisfy the equation. Second numbers in the pairs as components. 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. As an example, let us consider the distance traveled The language of mathematics is particularly effective in representing relationshipsīetween two or more variables.
