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:

The range could be written in inequality form will be $-2500\leq x\leq -100$.

Step-by-step explanation:

Slitsnails live in the deep water. It is given that they live between a depth of 100 ft to 2500 ft.

Let $x$ represents the depth of water from the water surface.

As we go down the water, the depth will be negative.

So, the depth could vary from 100 ft to 2500 ft.

The minimum depth should be 100 ft and the maximum depth is 2500 ft.

Thus, the range could be written in inequality form as,

$-2500\leq x\leq -100$

In a graph, the inequality can be shown as,
