Consider the equation y = –3(x – 3) Which equation, when graphed with the given equation, will form a system with lines that overlap? A)y = –3x – 9 B)y = –3x – 3 C)y = –3x + 3 D)y = –3x + 9

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.
