Math Problem Statement

Which of the following are solutions to the inequality -2 < q? Select all that apply.

Solution

The inequality provided in the image is:

2<q-2 < q

This inequality means that qq must be greater than 2-2.

Now, let's evaluate the possible values:

  1. q=1q = -1: Since 1>2-1 > -2, this satisfies the inequality.
  2. q=6q = -6: Since 6<2-6 < -2, this does not satisfy the inequality.
  3. q=10q = -10: Since 10<2-10 < -2, this does not satisfy the inequality.
  4. q=12q = -12: Since 12<2-12 < -2, this does not satisfy the inequality.

Thus, the only correct solution is q=1q = -1.

Do you need more details or have any questions?

Here are some related questions to consider:

  1. What happens if the inequality was q2q \geq -2?
  2. How do inequalities change when you multiply or divide by a negative number?
  3. Can we represent this inequality graphically on a number line?
  4. How would the solution change if the inequality was q2q \leq -2?
  5. What is the difference between strict inequalities and non-strict inequalities?

Tip: When solving inequalities, remember that multiplying or dividing both sides by a negative number reverses the inequality sign.
