Running head: TWO-VARIABLE INEQUALITIES 1 Two-Variable Inequalities Deanna Pates MAT 222 Week 2 Assignment Katherine Achacoso 08 Feb 2014
TWO-VARIABLE INEQUALITIES 2 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?
TWO-VARIABLE INEQUALITIES 3 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.
