Question

Question:
Solve the inequality and graph the solution on a number line. Negative four x is greater than or equal to twenty. Write the solution in inequality notation and interval notation. Explain what happens to the inequality symbol when you divide by a negative number.

Solving a One-Step Linear Inequality | Multiply or Divide

This lesson covers solving a one-step linear inequality that requires dividing by a negative number. Students learn the critical rule that dividing or multiplying both sides of an inequality by a negative number reverses the inequality symbol, and practice expressing solutions in inequality notation, interval notation, and on a number line.

In this lesson, you will learn to:
• Solve a linear inequality by isolating the variable using division
• Apply the rule that dividing by a negative number reverses the inequality symbol
• Express the solution in both inequ
