2x - 3y - 9z = -32
x + 3z = 8
-3x + y - 4z = -8
Add all the equations together.
-3y - 10z = -32
By looking at the first equation, 2x - 3y - 9z = -3y - 10z.
So 2x = -z.
By looking at the second equation, x + 3z = (-0.5z) + 3z = 8.
So 2.5z = 8, and z = 3.2.
This means that x = -1.6.
Let's substitute into our original equations!
-3.2 - 3y - 28.8 = -32
4.8 + y - 12.8 = -8
Therefore, y = 0!
Since these answers do not contradict each other, they are dependent.
The answers are x = -1.6, y = 0, z = 3.2.

Step-by-step explanation:
The match that can be made of these definitions are as follows
a. Space is the set of all points, lines, and planes. This definition is not understandable.
b. A radius is a chord containing the center of the circle. This definition is not accurate.
c. An angle is the union of two distinct rays, this definition is not concise.
<h3>What is space?</h3>
This is the term that is used to mean a continuous area or an expanse that is not occupied. The space is the free available area. When it is defined in this way, it would make the understanding of the word to be more possible and easier for the learner.
<h3>What is a radius?</h3>
This is used to refer to a straight line that is drawn from the center of a circle in such a way that it would have to touch the circumference of that particular circle.
<h3>What is an angle?</h3>
This is the space that is formed when two lines that are intersecting themselves at a particular point. When they meet they would have to form an angle.

Answer:
Because each word describes something completely different compared to the others. You normally do not hear of a hot winter or a wet desert.
