Find the error in the calculations below, if there is one: Line (1): 8x – 4 = 2(4x + 1) – 6 Line (2): 8x – 4 = 8x + 1 - 6 Line (3): 8x - 4 = 8x – 5 Line (4): -4 = - 5 Line (5): Based on the calculations above, there are no solutions. The error occurred from line (1) to line (2). The error occurred from line (2) to line (3). The error occurred from line (3) to line (4). The error is in line (5).​

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.
