Chapter 1.1, Problem 34E

To determine

a)

To graph:

The system $\begin{array}{rll}9x-4y& =& 5\\ \frac{1}{2}x+\frac{1}{3}y& =& 0\end{array}$ using graphing utility.

To determine

b)

To find:

Whether the system $\begin{array}{rll}9x-4y& =& 5\\ \frac{1}{2}x+\frac{1}{3}y& =& 0\end{array}$ is consistent or inconsistent using the graph.

To determine

c)

To find:

The approximate solution of the system $\begin{array}{rll}9x-4y& =& 5\\ \frac{1}{2}x+\frac{1}{3}y& =& 0\end{array}$ if it is consistent.

To determine

d)

To solve:

The system $\begin{array}{rll}9x-4y& =& 5\\ \frac{1}{2}x+\frac{1}{3}y& =& 0\end{array}$ algebraically.

To determine

e)

To compare:

The solution in part (d), with the approximate solution in part (c).
