|-11 + 12| = |-1|. Take away absolute value signs to get 1.
From the X axis it would be the Y access if that’s what you mean
Answer:
y=2x-4
I think this is right
Step-by-step explanation:
-4.8x + -2 (don't combine those because aren't like terms)
So, we know that it takes Sam 1 mph up and 9 mph down and it takes Liam both 2 mph down and up the hill. So if we divide the 2 mph for Liam by 2 miles (the whole length of the hill) we will get 1 or 1 hour. Then we do 1/1 (i don't know how to explain this part of why we do that, sorry) and than we do 1 / 9 and we get 1/9 so we add them and get 1 1/9 so that's Sam's time.
So, Liam took one hour and Sam took 1 and 1/9 hours, in conclusion liam was faster
