This type of problem can be solved by the substitution method for simultaneous equations. An
efficient alternative method is first to solve each equation for y and then graph the two functions on
a graphing calculator. You can then use the Intersect function to solve the system, arriving at the
points (1,6) and (−2,0). Choice (D) names one of these.
To solve the following volume problem, you can use the cube root, or key on the calculator. If
your calculator does not have this key, remember that you can use the power key and enter the
exponent of .
