Ineed an answer 30 points for use the constant of proportionality to write a unit rate for the data in the table. (i the constant is 45, so answer the question plz) write an equation to represent the relationship between time, t, and distance, d.

What is the solution to the equation 9^(x+1) =27

Which ordered pair (c,d) is a solution to the given system of linear equations- c+2d=13 -9c-4d=-15

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.
