Answer:

x = -0.95

Step-by-step explanation:

2e^-x+1 -5 = 9

2e^-x+1 = 9+5 = 14

e^-x+1 = 14/2 = 7

e^-x+1 =7

-x+1 = In 7 = 1.95

-x+1 = 1.95

x = 1 - 1.95 = -0.95

The intensity of a fire alarm that measures 125 dB loud is 268,337.29

<h3>Formula and expressions</h3>

Given the expression L=10 logI

where;

  • L is the loudness
  • I is the intensity of the sound.

Given the following parameters

L = 125dB

Substitute the given parameters into the following

L=10 logI

125 = 10logI

logI = 125/10

logI = 12.5

I = e^12.5

I = 268,337.29

Hence the intensity of a fire alarm that measures 125 dB loud is 268,337.29

2x - 3y = 25

+ (5x + 3y = 10)

=> 7x = 35, x = 5.

Therefore 2(5) - 3y = 25, 3y = -15, y = -5.

The solution pair is (5,-5).
