Question

Slitsnails are large mollusks that live in deep waters. They have been found in the range of elevations shown. Write and graph an inequality that represents this range. 100ft - 2500ft

Answer 1

Answer:

-100 ≥ x ≥ -2500

Step-by-step explanation:

The given figure show the range of elevations.

From the given figure it is clear that mollusks have been found in the range -100 ft to -2500 ft.

Let x be the depth of the water in which mollusks live.

Maximum value is -100.

$-100\geq x$

Minimum value is -2500.

$x\geq -2500$

On combining both inequalities we get.

$-100\geq x\geq -2500$

Therefore, the required inequality is -100 ≥ x ≥ -2500. The graph of inequality is shown below.

All points from -2500 to -100 are included in solution set. In the graph, red line represents the solution set. There are closed circle at -100 and -2500 because they are included in the range.

Answer 2

Answer:

-100 >= x >= -2500

Step-by-step explanation:

The range of the water is between and including -100 and -2500.
