Question 1

Which of the following is TRUE about solving inequalities?

Accepted Answer

You reverse the inequality sign when multiplying or dividing both sides by a negative number.

Question 2

Solve the inequality $$4x \u003c -4$$ and choose the correct solution.

Accepted Answer

$$x \u003c -1$$

Question 3

What is the solution to $$-2x \geq 6$$?

Accepted Answer

$$x \leq 3$$

Question 4

Which operation requires you to reverse the direction of the inequality sign?

Accepted Answer

Accepted Answer

$$-2a \u003e -2b$$

Question 7

Which of the following is the correct first step to solve $$4x - 6 \u003e x - 5$$?

Accepted Answer

Subtract $$x$$ from both sides

Question 8

Solve the inequality $$7 - 3x \leq 19.$$

Accepted Answer
