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.

Olympic 5000-Meters The accompanying graph shows the winning time (in minutes) at the Olympic Games from 1952 to 2016 for the men's 5000-meterrun, together with a linear approximation of these data. (Data from: The WorldAlmanac and Book of Facts: 2017.)

Chapter 2.2, Problem 78E, Olympic 5000-Meters The accompanying graph shows the winning time (in minutes) at the Olympic Games

The equation for the linear approximation is y = − .0135 x + 40.32 , where x is the actual year.

Cocoa Production In 2005, global cocoa bean production was approximately 3.3 million metric tons. In 2015, production wasapproximately 4.1 million metric tons. (Data from: The Wall StreetJournal.)

a. Write a linear equation expressing cocoa bean production y in terms of the number of years x after 2000.

b. What was the cocoa bean production in 2012?

c. If the trend continues, what will be the first full year in which cocoa bean production exceeds 5 million metric tons?

7. [10 marks] Let G = (V,E) be a 3-connected graph. We prove that for every x, y, z Є V, there is a cycle in G on which x, y, and z all lie. (a) First prove that there are two internally disjoint xy-paths Po and P₁. (b) If z is on either Po or P₁, then combining Po and P₁ produces a cycle on which x, y, and z all lie. So assume that z is not on Po and not on P₁. Now prove that there are three paths Qo, Q1, and Q2 such that: ⚫each Qi starts at z; • each Qi ends at a vertex w; that is on Po or on P₁, where wo, w₁, and w₂ are distinct; the paths Qo, Q1, Q2 are disjoint from each other (except at the start vertex 2) and are disjoint from the paths Po and P₁ (except at the end vertices wo, W1, and w₂). (c) Use paths Po, P₁, Qo, Q1, and Q2 to prove that there is a cycle on which x, y, and z all lie. (To do this, notice that two of the w; must be on the same Pj.)
