Does inline code affect seo? If yes, how much?

Answer 1

has no direct influence.
however, using inline we get several side effects:
- increase in page size and load time
- inline code is not cached
- development/refactoring becomes more complicated
On the other hand, inline can slightly increase "speed":

For best performance, you may want to consider inlining the critical CSS directly into the HTML document. This eliminates additional roundtrips in the critical path and if done correctly can be used to deliver a “one roundtrip” critical path length where only the HTML is a blocking resource.

The main thing is to find your middle ground and not overdo it.
