ALGEBRA II HELP PLSSS An equation for loudness L in decibels is given by L = 10 log R, where R is the relative intensity of the sound compared to the minimum
threshold of human hearing. One city's emergency weather siren is 138 decibels loud. How many times greater than the minimum threshold of
hearing is the siren? Write your answer in scientific notation with one decimal place.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
