Imagine this:
The altitude of an airplane coming in for a landing is represented by the equation shown below, where y represents the
altitude, in feet, of the airplane and x represents the number of minutes the plane has been descending:
y = -750x + 30,000
Part A:
Create a table for the values when x = 0,5, 8, 10, 30.
-
Include worked-out equations used to identify the values within the table.
Part B:
dentify the altitude after 5 minutes and after 30 minutes. Use 1-2 sentences to explain the altitude at these two times
and describe what is happening to the airplane at these time intervals.

Answer:

Part A

Input each value if x into the equation to find y:

x           y      

0      30,000

5      26,250

8      24000

10    22,500

30      7,500

Part B

The altitude after 5 minutes is 26,250 feet, and after 30 minutes is 7,500 feet.

Just put x values from domain and get y
