Suppose you have a square matrix a for which det (a)? o. tell whether each of the following is true or false. support your answer (a) (2 points) a-1 exists (b) (2 points) a is invertible (c) (2 points) ar-0 has exactly one solution (d) (2 points) at has no solution. (e) (2 points) the reduced row echelon form of a has a row of zeros in (f) (2 points) the columns of a are linearly independent

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)
