Step-by-step explanation:
this is only asking about the functional values.
in what intervals are the functional values going up (when increasing x from left to right), and in what intervals is the functional value going down (again, when increasing x from left to right) ?
and so we see in the graph,
it is increasing (y-values are going up) in
(-infinity, -1], (2, +infinity)
it is decreasing (y- values are going down) in
(-1, 2]
please consider the used types of brackets.
"(", ")" means the corresponding interval end is NOT included.
"[", "]" mags the corresponding interval end is included.
"infinity" is only a concept and not a value, so it can never be included.
and I wanted the intervals to have no overlap. so, I included "-1" in one and excluded it in the connecting interval. the same for "2".
but if your teacher prefers to have the interval ends overlapping, then please change these brackets to "["as needed. it all depends on what your teacher defined for you.

Answers
This system of equation has an infinite number of solutions.
You can tell this because multiplying one equation by a constant gives you exactly the other equation. You can multiply the second equation by 3.
9x - 6y = 15
5(3x - 2y = 5) = 9x - 6y = 15
When this happens, you can assume that there are an infinite number of solutions.
Answer:
1) The equations in the system are equivalent equations.
2) There is no solution to the system of equations.
3) The system of equations has one solution at (3, 2).
4) The system of equations has one solution at (5, 5).

You need the starting point, and another point that helps direct where the ray is aimed. Call these two points A and B.
Saying "Ray AB" means we extend a line through AB such that the line goes forever through B and beyond B, but we do not do the same for point A. The point A is effectively a cliff where no road goes on the other side of it. Check out the diagram below to see what I mean. The arrow means the line goes on forever in that direction.

This is because both of those angles are equal, so you would divide 42 by 2 and get 21
