Review Questions

• Explain how algebraic manipulation is used to solve a formula for a specific variable.
  • To solve a formula for a specific variable, algebraic manipulation involves isolating that variable by performing inverse operations and rearranging the terms in the equation. This may include dividing both sides by the coefficient of the variable, moving terms to one side of the equation, and applying the properties of equality to isolate the desired variable. The goal is to transform the original formula into an equation that explicitly solves for the target variable.
• Describe the role of algebraic manipulation in solving linear inequalities.
  • Solving linear inequalities requires the use of algebraic manipulation techniques, such as adding, subtracting, multiplying, or dividing both sides of the inequality by the same value, while maintaining the direction of the inequality sign. This allows for the isolation of the variable and the simplification of the expression, ultimately leading to a solution set that satisfies the original inequality.
• Analyze how algebraic manipulation is applied to solve absolute value inequalities.
  • Solving absolute value inequalities involves a multi-step process of algebraic manipulation. First, the absolute value expression is isolated on one side of the inequality. Then, the inequality is split into two separate inequalities, one for the positive case and one for the negative case. Algebraic techniques, such as squaring both sides or using the properties of absolute value, are applied to each inequality to find the solution sets, which are then combined to determine the final solution to the original absolute value inequality.
