1. points a and b are to be mapped onto a number line according to two equations. the solution to the equation is the coordinate of point a. the solution to the equation is the coordinate of point b.
(a) solve the first equation to find the coordinate of point a. need quick

What is the missing step in this proof ?

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.
