The answer to this equation is x=11

5(x-2) = 3(x+4)

5x-10 = 3x+12
-3x -3x

2x-10 = 12
+10 +10

2x = 22

x= 11

Hope this helps :)

A decibel is a logarithmic unit that can be used to measure the intensity of a sound. The function y = 10logx gives the intensit
Anna007 [38]

Answer:

The sound intensity of a whisper is 333.3 times the reference intensity

Step-by-step explanation:

Given : The function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity.

A whisper has a sound intensity of 30 decibels.

To find : Use your graph to help you complete the following statement. The sound intensity of a whisper is times the reference intensity.

Solution :

Graph is attached which shows their intersection at (1000,30).

We can also verify by substituting value.

We have given that a whisper has a sound intensity of 30 decibels.

Therefore, y=30 , Let log base 10

y = 10logx

30 = 10logx                              

\frac{30}{10} =logx

3=logx

Logarithmic property log_{x}b=a \Rightarrow b=x^a

x=10^3

x=1000

The ratio of the intensity of the sound to a reference intensity is 1000 decibels

The sound intensity of a whisper is times the reference intensity is

\frac{1000}{3}=333.33

The sound intensity of a whisper is 333.3 times the reference intensity.
