To evaluate the expressions, you substitute -9 for x and 3 for y into the expressions
(4y)^2 - (2x)
= (4(3))^2 - (2(-9))
= (12)^2 - (-18)
= 144 + 18
= 162
4y^2 - 2x^2
= 4(3)^2 - 2(-9)^2
= 4(9) - 2(81)
= 36 - 162 = -126
Neither A, B or D explains why plane is undefined. All 3 of those answers describe something about plane which is true. Plane indeed can be named using three non collinear points. However, B is telling why plane is undenified. I it described generally, not using a formal definition.
Answer is B
Answer:
the last one makes more sense compared to all the other choices.
The difference is in way we observe some object that is moving. In translatory motion each point of the object has to go in straight line. A ball for example when kicked is rolling which means that not all of its oints are going in straight line. Some of points on ball are rotating. On the other hand in rectilinear motion it is only important that object is moving on straight line and it doesnt matter if it is rotating. So kicked ball that moves on ground is example of that.
Example of translatory motion can be our body in a bus that is going in straight line but not that wheels are rotating so they are moving rectilinear.
Is there an image or some information about the line?
I can't tell you which of these is true without more information.
