The number of text messages, y (in billions), sent in the United States since 2005 can be modeled using
the equation y=18.813)*,where x is the number of years after 2005. In what year were there
approximately 4,6 trillion text messages sent?

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)
