The equation p=100−4t represents the percent p of battery power remaining in an MP3 player after t hours.

a. Identify the independent and dependent variables. Then describe how the battery power changes over time.

The independent variable is
and the dependent variable is
.
The battery power begins at ☐ % and decreases ☐ % each hour.

Question 2
b. Graph the equation.

Respuesta :

Answer:

Step-by-step explanation:

Here time (t) is the independent variable; power (p) is the dependent one.

The graph of p = 100 - 4t is a straight line with slope -4.  100 is the vertical intercept.  Battery power begins at 100 and steadily decreases after that.
