B. (f + g)(x) less than equal to 3 for all values of x
C. (f + g)(x) less than equal to 6 for all values of x
D. (f + g)(x) more than equal to 6 for all values of x

Evaluate the expression for the given value of the variable. 5×(h+3) for h=7

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.

Rewrite so the subject can be y in the formula d=m-y/y+n
