4 = 1/5 x
x = 20
There were 20 problems on the test.

<span>One of the main characteristics of rational functions is the existence of asymptotic. An asymptotic is a straight line to which the graph of the function
gets arbitrarily close. ... Vertical: These are the equations of the
straight lines (if any) the one gets by setting the linear factors of
