Graphing calculators will be used to confirm algebraic solutions. Solve linear equations using the addition, subtraction, multiplication and division properties of equality. Solve linear inequalities using the addition, subtraction, multiplication, and division properties of inequality and picture the solution on the number line. Create and use algebraic models to solve real-life problems.
Check answers using the graphing calculator.
Solve a literal equation for a specified variable. The student will represent verbal quantitative situations algebraically and evaluate these expressions for given replacement values of the variables. Students will choose an appropriate computational technique, such as mental mathematics, calculator or paper and pencil. Add, subtract, multiply and divide real numbers. Simplify and evaluate algebraic expressions using order of operations and grouping symbols.
