Sample Problems

 

Once you have reviewed the six modules above, take a stab at these practice problems.

 

 1.  True or False:  ln(8) = ln(4) + ln(4)

 

2.  Simplify:  6!/8!

 

3.  What is the slope of the line  3x + 5y = 10?

 

4.  Solve for x and y:

                    10x + 3y = 20

                    5x –   2y = 10
