Why all these kids playing league if they just going to feed

So I've played 5 games and all of these games are complete losses. It's not because of me it's because of my team feeding lane. It's really heavy to carry them. Some of them afk cuz they cant figure out how to deal with their enemy. It is so stressful losing games bcuz of teammates feeding. Im trying to climb up to gold but my teammate drags me down. How do i deal with this? If they just dont know how to play smarter they should quit league.
