#6 is F=15b ( this is because 30/2 is 15 and it matches with all the other ones)
#7 is Y=3x ( for every x movies she gets 3 points )
#8 is G ( the amount earned each week depends on how many hours you work therefore it’s the dépendant variable)
#9 is D
#10 is F ( if x=x then A will always be larger, think of it like this: if x=5 for example then which one would be greater? 5+5 or 5(5)
Hope this helps, I’m not that good at explanations
