In brief: Incomplete killing
Mutations in bacteria that lead to resistance can occur when bacteria are exposed to antibiotics in doses that are not strong enough to kill them. The bacteria then can mutate and develop resistance.
A favorite professor of mine would always say "dead bacteria can't develop resistance.".

In brief: Antibiotics
Bacteria have a great ability to genetically adapt to their environment.
After an exposure to a specific antibiotic, a bacterium can modify its genetic makeup to create particular barrier(s). Overuse of antibiotics, inadequate dosing and incomplete dosing can all contribute to the emergence of resistance.
