Graph the following:
X+y=-4
Y=2x+1

What are the steps to solving the inequality 3b + 8 ≥ 14?

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.

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x
