If you have the inequality -7 ≤ a - 3, what is the first step to solve for a?

• Multiply both sides by -3

• Divide both sides by -3

• Add 3 to both sides

• Subtract 3 from both sides

When graphing the solution a ≥ -4, what type of circle do you use at -4?

• Closed circle

• Double circle

• No circle

• Open circle

What should you do when you multiply or divide both sides of an inequality by a negative number?

• Keep the inequality symbol the same

• Flip the inequality symbol

• Subtract a positive number from both sides

• Add a positive number to both sides

What is the result of dividing both sides of the inequality -9n > 63 by -9?

• n < 7

• n > 7

• n < -7

• n > -7
