Write a doubles plus one fact for the sum of 7

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

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.

The points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?
