Tuesday, Jan 28 Chapter 8.7 Solve One-Step Inequalities

Objective: To addition and subtraction inequalities.

Solve One-Step Inequalities At the end of this lesson you should be able to answer the following question. How is solving and inequality the same as solving an equation?

Solve One-Step Inequalities If you add or subtract the same number from each side of an inequality, the inequality remains true. This is the same as an equation.

Solve One-Step Inequalities Solve x + 7 > 10. To Solve an Addition or Subtraction Inequality. Step 1- Determine which side of the inequality has a variable and constant.

Solve One-Step Inequalities Solve x + 7 > 10. To Solve an Addition or Subtraction Inequality. Step 2 - Add the opposite of the variable side constant to both sides, making sure to line up the constants.

Solve One-Step Inequalities Solve x + 7 > x > 3 Graph the inequality.

Solve One-Step Inequalities Solve x + 7 > x > 3 Graph the inequality.

Solve One-Step Inequalities Solve x - 3 < 9. Then graph the inequality. Do this on your own.

Solve One-Step Inequalities Solve x - 3 < 9. Then graph the inequality x < 12

Solve One-Step Inequalities Solve n + 2 > 2. Then graph the inequality. Do this on your own.

Solve One-Step Inequalities Solve n + 2 > 2. Then graph the inequality n > 0

Solve One-Step Inequalities If you multiply or divide the same number from each side of an inequality, the inequality remains true. This is the same as an equation.

Solve One-Step Inequalities Solve 5x < 45 To Solve a Multiplication or Division Inequality Step 1 – Determine the coefficient.

Solve One-Step Inequalities Solve 5x < 45 To Solve a Multiplication or Division Inequality Step 2 – Multiply both sides by the reciprocal of the coefficient.

Solve One-Step Inequalities Solve 5x < x < 9 Graph the inequality.

Solve One-Step Inequalities Solve 5x < x < 9 Graph the inequality.

Solve One-Step Inequalities Solve 10x < 80. Then graph the inequality. Do this on your own.

Solve One-Step Inequalities Solve 10x < x < 8 Graph the inequality.

Solve One-Step Inequalities Solve x > 2. Then graph the inequality. 6 Do this on your own.

Solve One-Step Inequalities Solve x > 2. Then graph the inequality. 6 6 · x 2 · 6 1 · 6 > 1 · 1 x > 12

Solve One-Step Inequalities Laverne is making bags of party favors for each of the 7 friends attending her birthday party. She does not want to spend more than $42 on party favors. Write and solve an inequality to find the maximum cost of each party bag. Do this on your own.
