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 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.
