****Answers could be different depending on state and which course you're taking. These were the correct answers for me.****
Then why are you also here cheating if its as you say "it does not benefit you what so ever" um ur also here so shoosh lol
why would u be on this website then.. if cheating is bad? we come here to check our work to make sure that we did everything correctly. well that is for me. anyways thanks n/a for the help!
@N/a is 100% correct, but there's a typo in the 1st answer. it's (-1/2, -5/2), (2, 5)
I think a teacher or another student renamed themselves as N/a and said the answers were wrong so no one cheats, so don't worry the answers are right.
wait, unit 5? isnt this unit 4..?
