Composition of functions f(x)=x-4 g(x)=[x/6] h(x)=x* (g•h•f)(5)

It says factor each expression completely 8y+48

Use the elimination method to solve the systems of equations. choose the correct ordered pair. 7x+4y=39

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.
