TWO-VARIABLE INEQUALITIES

Two-Variable Inequalities
Continuing last week’s topic of functions and relationships between variables, this week’s work
examines a practical application of two-variable inequalities. As the name implies, there are
independent and dependent variables, as well as graphic representations of the solutions. Because
of the inequality, the graphs and solutions demonstrate a range of possible answers that would
work in the given situation.
Shipping restrictions.
The accompanying graph shows all of the possibilities for the number
of refrigerators and the number of TVs that will fit into an 18-wheeler.
a)Write an inequality to describe this region.
b
)
Will the truck hold 71 refrigerators and 118 TVs?
c)Will the truck hold 51 refrigerators and 176 TVs?

An 18-wheeler can carry maximum of 110 refrigerators and no TVs, or maximum of no
refrigerators and 330 TVs recliners. We study the graph and write an equation to fit the line. We
pretend the triangle region is shaded in and change the equation to an inequality describing this
region.
