A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
Answer:
72
Step-by-step explanation:
80x.90= 72
The rate of change of the plane's altitude is 2250 feet per minute.
<h3>How to calculate the rate?</h3>
The rate of change of the plane's altitude will be:
= (35000 - 17000)/8
= 18000/8
= 2250 feet per minute.
When graphing the descent of the plane, the starting value for its altitude be 35000 feet.
The linear function will be:
y = mx + b
35000 = 2250x + b
35000 = 2250(0) + b
b = 35000
y = -2250x + 35000
The information given in this problem that did not need to write an equation for the descent is the initial details about how long that the plane travelled.
