Question

Find all real numbers x such that

3x - 4 > 5 or -8x - 19 > 21
Click on the correct answer.

Answer 1

Option B

Explanation:

3x - 4 > 5

3x > 9

x > 3

-8x - 19 > 21

-8x > 40

x < -5

This means that we can eliminate the first option, since it includes all real numbers. We can also eliminate the last option since it doesn't include any real numbers.

The middle option is the only graph that includes numbers from -∞ to -5, and 3 to ∞
