Rhett was solving the algebraic proof below. What reason is missing from his proof?
2(3x - 4) + 5x = -41 Given
(6x - 8) + 5x = -41 Distributive Property
6x + 5x -8= -41
?
11x - 8 = -41 Write an equivalent equation
11x = -33 Addition or Property of Equality
x = -3 Division Property of Equality

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. 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. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
