Question

One layer of Earth's atmosphere is called the stratosphere. At one point above Earth's surface the stratosphere extends from an altitude of 12 km to an altitude of 40 km. Enter a compound inequality to show the altitudes that are within the range of the stratosphere, use k as the altitude variable. Graph the solutions.

Answer 1

Explanation:

lk

Answer 2

Explanation:

The Stratosphere is

Stratosphere = 12 < k < 40

It means that the stratosphere is larger that 12 km above the earth's surface to less than 40 km above the earth's surface.

The value of x or the x axis does not matter. Only the y or k value matters.
