Answer:
<em>The sound level would be at 80 decibels at 1 or 7 number of measures played</em>
Step-by-step explanation:
<u>Equations with Absolute Values</u>
We have the function s to represent the sound level in decibels:
Where x is the number of measures of the music played.
We are required to find the value of x that makes s=80 decibels. We have to find the equation:
Subtracting 50:
Dividing by 10:
For the absolute value be equal to 3, its argument could be positive or negative:
Or
This leads us to two solutions:
x=7
Or
x=1
The sound level would be at 80 decibels at 1 or 7 number of measures played
