Solving a one step inequality using division

The video tutorial explains how to solve a one-step inequality by dividing both sides of the inequality by a number. It demonstrates how to graph the solution on a number line, emphasizing the use of a closed dot for 'greater than or equal to' inequalities. The tutorial also covers testing points to verify the solution, ensuring that the inequality holds true for values greater than the specified number.

What is the first step in solving the inequality 20B ≥ -120?

• Subtract 20 from both sides

• Divide both sides by 20

• Multiply both sides by 20

• Add 120 to both sides

When graphing the inequality B ≥ -6 on a number line, what type of dot is used at -6?

• No dot

• Half-filled dot

• Open dot

• Closed dot

Which direction on the number line represents numbers greater than -6?

• Left

• Right

• Up

• Down

How can you verify if a number satisfies the inequality B ≥ -6?

• By plugging it into the inequality and checking if it holds true

• By checking if it is equal to -6

• By adding 6 to it

• By checking if it is less than -6

Which of the following numbers satisfies the inequality B ≥ -6?

• -8

• -7

• -5

• -6
