The graphs of inequalities often intersect. Let's look at a simple one.
x<5 and x>4. The intersection is all x such that x>4 and x<5
or those numbers between 4 and 5 not including 4 and 5 itself.
If I want to include 4 and 5, just change it to < or = instead of strict
inequality.
Sometimes there is not an intersection. For example, x < 4 and x > 4, or x < -4 and x > 5, ... .

When is system of linear inequalities have no solution?
When the lines never intersect, usually when they are parallel.
Lines never intersect?
Parallel lines never intersect
2 lines that will never intersect?
Parallel straight lines never intersect.
Do parallel intersect?
no they are straight lines that never intersect, intersecting lines intersect.
Can parallel lines intersect?
No, never. Parallel lines are line that will NEVER intersect.
What are lines that do not intersect called?
Lines that never intersect are parallel.
Will pallel line intersect?
Parallel lines never intersect.
Where do parallel lines intersect?
In Euclidean geometry, parallel lines never intersect. They go this way forever and never intersect but watch this typing. _______________ _______________ In non-Euclidean geometry, they intersect when the faces are uneven.
Are lines that never intersect parallel or perpendicular?
parallel ============================================= Parallel. _____________________ _____________________ Those two lines will NEVER intersect.
How do you solve questions that say which graph best represents the system of inequalities?
The solution to a system of inequalities is where the solutions to each of the individual inequalities intersect. When given a set of graphs look for the one which most closely represents the intersection, this one will contain the most of the solution to the the system but the least extra.
Two lines that on the same plane that never intersect?
parallel lines If they are not on the same plane and never intersect they are skew
What shape has lines that never intersect?
A common shape that has lines that never intersect is the equals sign. Shapes that include intersecting lines but also have others that will never intersect include squares, rectangles, and rhombuses.
