Describe the value of the 9 in 926,415. explain

If 3x+8=3x+8 is it one solution or no solution

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

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.
