Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}

Answer:
L = 9.91 decibels.
Step-by-step explanation:
The loudness, L is inversely proportional to the square of the distance, d, from the source of the sound.
i.e L
![\frac{1}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bd%5E%7B2%7D%20%7D)
L = ![\frac{k}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bk%7D%7Bd%5E%7B2%7D%20%7D)
Where k is the constant of proportionality.
When d = 14 feet and L = 85 dB, then;
k = L x ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
= 85 x ![(14)^{2}](https://tex.z-dn.net/?f=%2814%29%5E%7B2%7D)
= 16660
k = 16660
L = ![\frac{16660}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B16660%7D%7Bd%5E%7B2%7D%20%7D)
Thus, when d = 41 feet, then;
L = ![\frac{16660}{(41)^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B16660%7D%7B%2841%29%5E%7B2%7D%20%7D)
= ![\frac{16660}{1681}](https://tex.z-dn.net/?f=%5Cfrac%7B16660%7D%7B1681%7D)
= 9.91077
L = 9.91 dB
The loudness is 9.91 decibels.
