Which expression is equivalents to 7y+4y+3x+6y-x ?

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

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.

Answer! if you don’t mind, can you explain
