Was given a car with tons of problems. Where should i start?

2009 BMW 128i.

Im going to put a new battery in today and see what that fixes.

The car does not react to any throttle. I press the gas pedal down but the RPM’s dont go up. The car moves at a very slow idle speed though.

Any ideas on where to start? Thanks.
