Final answer:
A machine made up of two or more simple machines working together is called a compound machine. Complex machines are combinations of simple machines that work together to achieve a specific task. The combination of these simple machines allows the bicycle to function as a complex machine.
Step-by-step explanation:
A machine made up of two or more simple machines working together is called a compound machine. Complex machines are combinations of simple machines that work together to achieve a specific task.
