Answer:
Well the answer would be 3 inches to figure it fully out my best guess is 3
Step-by-step explanation:
Answer:
Explanation:
<u>1. Given equation:</u>

<u>2. Given intensity:</u>

<u>3. Decibels</u>

Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
