Question

9 notah is studying ocean animals. he learns that the sixgill shark can dive to an elevation of about -8,200 ft relative to sea level and the elephant seal can dive to an elevation of about -7,800 ft. write an inequality to compare these elevations. which animal can dive to a lower elevation? show your work.

Explanation:

Step1: Recall negative number comparison

For negative numbers, the larger the absolute value, the smaller the number. So we compare \(-8200\) and \(-7800\).

Step2: Write the inequality

Since \(8200>7800\), then \(-8200 < -7800\).

Step3: Determine lower elevation

A lower elevation means a more negative (or smaller) number. Since \(-8200 < -7800\), the sixgill shark (with elevation \(-8200\) ft) dives to a lower elevation.

Answer:

The inequality is \(-8200 < -7800\). The sixgill shark can dive to a lower elevation.
