Help I don't know this outside: its time to do my homework its time to be productive
in my head: We did not learn this.

Me with this one question, and i'll upvote the brainliest answer

Solve the system of equations y= 3/2 - 1, -x+ y =-3

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.
