1)a linear function is represented by f(x)=2x+7 which of the following functions would be parallel to that of the function above
a)f(x)=2x-7
b)f(x)=x+7
c)f(x)=x-7
d)f(x)=-1/2x+7
e)f(x)=-1/2x-7
I choose b

2)water is pumped into an empty tank at a constant rate. after 2 minutes the tank contains 400 gallons. after 5 minutes the tank is full. how many gallons of water does the tank hold

900 gallons

the one with the same slope of 2.
I choose (a)

Looks like it gets water at the rate of 200 gallons/minute. How do you get 900 after 5 minutes of pumping?
