Since the lines that intersect are the equations, if they intersect once they have one solution.

Why the imaginary lines of magnet never intersect?
If they would intersect, that would mean that at one point in space, the field lines point to two different direction simultaneously. A compass needle would have to point to two different directions at once.
When you solve a system of equations algebraically how can you tell whether the system has zero one or an infinite number of solutions?
Compare the equations. If it has the same slope it most likely will be parallel which means it has 0 solutions. However, if you plug in points and they match up exactly it would have an infinite amount of solutions. The only way it would intersect more than once or 2 then would be if it was a parabola which would have a x^2 value typically. If it has 1 solution it means it would intersect once.
How many times does each line segment in a polygon intersect?
I want to say 2, once at each corner
How many times do a pair of intersecting lines cross?
Once.
How many times do two intersecting lines cross?
once
Three lines can intersect in only two points?
This is true. If three straight lines are drawn, they can only intersect at two points. That is, each line will only intersect with another once.
Why does a pair of intersecting lines cross only once?
They only cross once because intersecting lines are only supposed to INTERSECT at one point, hence the name intersecting lines
Can two rays intersect in more than one point?
no the definition is two lines intersecting once

Can two segments intersect more than once?
no yes of course. they can intersect infinite times when they coincide

What is the maximum number of times 2 planes can intersect?
In three-dimensional space, two planes can either:* not intersect at all, * intersect in a line, * or they can be the same plane; in this case, the intersection is an entire plane.
How many times do two intersecting lines cross?
once
How many times do a pair of intersecting lines cross?
Once.
When parrarel lines meets?
For most purposes in algebra and geometry, but especially geometry, parallel lines never meet. This should be the answer you give on nearly every question. However, speaking realistically, parallel lines can meet on planes of negative and positive curvature. An example of positive curvature would be a sphere; on a sphere, if you try to draw a triangle, the interior sum would be more than 180degrees and parallel lines would intersect. Similarly, on a plane of negative curvature like that of a surface of a saddle, the sum of the measures of the triangle would be less that 180 degrees and once again parallel lines will intersect.
How many points does the graph of the function below intersect the x-axis y25x2-10x 1?
Just the once because it has equal roots of 1/5
