we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
