solve the inequality of 1/11c greater or equal to 9
the inequality is: 1/11c <= 9
There are two possibilities here, 1) that c is positive. 2) that c is negative
c positive c negative
multiply both sides of multiply both sides of
the inequality by 11c, the inequality by 11c,
giving reverse the direction of the inequality
1 <= 99c 1 >= 99c
c >= 1/99 c <= 1/99
