Question

Which compound inequality is equivalent to the absolute value inequality |3x|≥0

Answer 1

Explanation:

The absolute value of any real number is always non-negative (greater than or equal to zero). Therefore, the absolute value inequality |3x| ≥ 0 is always true for all values of x. In other words, it's a universal inequality that holds for every real number.

So, the equivalent compound inequality is:

For all real x: -∞ ≤ x ≤ +∞

This inequality essentially states that x can be any real number, which is always true.
