Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Chapter 7.3, Problem 53E

Bottled Water Sales The rate of U.S. sales of bottled water for the period 2007–2014 could be approximated by

s ( t ) = 0.08 t 2 − 0.26 t + 8.8  billion gallons per year ( 0 ≤ t ≤ 7 ) , where t is time in years since the start of 2007.34

a. Estimate the average annual sales of bottled water over the period 2007–2014, to the nearest 100 million gallons per year. [HINT: See Quick Example 2.]

b. Compute the 2-year moving average of s. (You need not simplify the answer.) [HINT: See Quick Example 3.]

c. Without simplifying the answer in part (b), say what kind of function the moving average is.

World Population The low long-range world population numbers and projections for the years 1995–2150 are given by the equation y = -0.00036x2+0.0385x + 5.823, where x is the number of yearsafter 1990 and y is in billions. During what yearsdoes this model estimate the population to be above6 billion?
In Exercises 7–12, describe the relationship between the two quantities.
U.S. Population The number of White non-Hispanicindividuals in the U.S. civilian non-institutional population 16 years and older was 153.1 million in 2000and is projected to be 169.4 million in 2050.(Source: U.S. Census Bureau)a. Find the average annual rate of change in population during the period 2000–2050, with the appropriate units.b. Use the slope from part (a) and the population in2000 to write the equation of the line associatedwith 2000 and 2050.c. What does this model project the population to bein 2020?
