Question

elevations are measured compared to sea level. an elevation of 0 feet is \at sea level.\ an elevation less than 0 feet is \below sea level.\ which two of these elevations are below sea level? -5 ft -2 ft let x be an elevation. write an inequality to represent elevations below sea level. x? 0

Explanation:

Part 1: Which TWO elevations are below sea level?

Elevations below sea level are less than 0 (since 0 is sea level). -5 ft and -2 ft are both less than 0, so these are the two elevations below sea level.

Step1: Recall the definition

Elevations below sea level are less than 0 (since sea level is 0). Let \( x \) be the elevation.

Step2: Form the inequality

Since \( x \) (elevation) is below sea level, it must satisfy \( x < 0 \).

Answer:

-5 ft, -2 ft

Part 2: Write the inequality for elevations below sea level
