Answer:
If you simplify the equation, you will get, 
Step-by-step explanation:
You have to combine like terms.
and 
are like terms, so you add them together.
The answer is D.
The full specification of Newton's First Law is (from Wikipedia)
In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.
On earth we're generally in slightly a non-inertial frame, with rotation and revolution around the sun. It's also impossible to turn of gravity, so objects are being acted upon by an outside force. Typically there's also the outside force of friction, which makes things tend to stop.
Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.
Hope this helps, have a great day.

1. Substitute y=-x+2 into x-3y=-18:
x-3(-x+2)=-18,
x+3x-6=-18,
x+3x=-18+6,
4x=-12,
x=-3.
Then y=-(-3)+2=3+2=5.
2. The graphs of two equations you can see in attached diagram. Common point (the point of intersection) represents the solution of the system of two equations.
Answer: (-3,5) or x=-3, y=5.
