1. One-step inequalities examples
Our discussion of linear inequalities begins with multiplying and dividing by negative numbers. Listen closely for the word "swap." Super important!
2. One-step inequalities: -5c ≤ 15
In addition to solving the inequality, we'll graph the solution. Remember to swap if you mutiply both sides of the inequality by a negative number.
3. One-step inequality word problem
Inequalities are more than abstract concepts and exercises. They help solve real life problems. Here's an example.
7. Two-step inequalities
We're turning up the heat a little and asking you to help us solve a multi-step inequality problem.
10. Inequalities with variables on both sides (with parentheses)
Sal solves the inequality 5x+7>3(x+1), draws the solution on a number line and checks a few values to verify the solution.
11. Inequalities with variables on both sides
Sal solves the inequality -3p-7<p+9, draws the solution on a number line and checks a few values to verify the solution.
