So just divide 27 by 4 1/2 or 4.5, you should get 6 so it would take 6 hours for the snow to get to 27 inches
I think its 6 but im not sure
ANSWER
A) For all x > 0 the graph will be higher.
EXPLANATION
Jack's graph has equation
y=2x
This graph passes through the origin and has slope 2.
Nina's graph is y=5x.
This graph also passes through the origin and has slope 5.
Since 5 is greater than 2, for all x>0, Nina's graph will be higher.
