Write a function g whose graph represents a vertical shrink by a factor 1/2 of the graph of f(x) = 2x + 6

Solve 2x+y=3 x+y=5 in substitution method

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.

Could someone me with this question i’ve been stuck on it for 20 minutes
