Included a pic of the solution and work.
If two lines have the same slope, then they are always parallel, unless they are the same line. Parallel lines means they never touch, but if you have the same line, they would be touching.
If two lines have the same slope and y-intercepts, then they are the same line, therefore not parallel because they touch each other.
Answer: The tank which has 3 m side.
Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:
V = length*width*height
Since they are all the same, volume will be:
V = s³
One tank has a 3 m side, so its volume is:
V = 3³
V = 27 m³
The other has half of the first one side, then s =
and volume will be:
V = 
V =
m³
As you can see, the volume of the second tank is
smaller than the first one. Therefore, the tank which has 3 m side can store more water than the tank with side measuring half of the first.
That would be False, if you were to graph it it pases far from (7,1)
316 ? I think pretty sure though ♀️
