Answer :
The inequality means that x, representing the depth in meters, is greater than or equal to 4,000 meters and less than or equal to 6,000 meters.
A compound inequality to represent the range of depths in the abyssopelagic ecosystem.
The abyssopelagic zone consists of the deeper parts of the open ocean, which range between 4,000 and 6,000 meters below sea level.
To represent this range in a compound inequality with the variable x, we write:
[tex]4000 \leq x \leq 6000[/tex]
