Answer 2

The compound inequality will be "$x \geq 29,000 \ and \ x \leq 41,000$". A complete solution is provided below.

Let,

The altitude of a commercial aircraft will be:

= x

According to the question,

The minimum altitude will be:

• $x \geq 29,000$

The maximum altitude will be:

• $x \leq 41,000$

hence,

All the real numbers are $\geq$ 29,000 feet and $\leq$ 41,000 feet.

→ The compound inequality will be:

= $x \geq 29,000 \ and \ x \leq 41,000$

Thus the above answer is the correct one.
