To indicate a restriction or condition in a real-world or mathematical situation, write an inequality of the type x > c or x c. Recognize that inequalities of the type x > c or x c have an unlimited number of solutions; show such solutions on number line diagrams. Create a formor inequality to describe a restriction or condition in a real-world or mathematical situation. Recognize that inequalities of the type c have an unlimited number of solutions; display such solutions on number line diagrams. Quantitative connections between dependent and independent variables must be represented and analyzed.

To simplify a numerical equation, do all feasible math. For example, [latex]4cdot 2+1[/latex] may be simplified. We'd multiply [latex]4cdot 2[/latex] to obtain [latex]8[/latex], then add [latex]1[/latex] to get [latex]9[/latex]. Working down the page, writing each step of the procedure below the previous step, is an useful habit to acquire. The following is an illustration of what I mean: [latex][latex]4cdot 2+1[/latex]
