A closed dot includes the number, an open dot excludes the number. Greater than excludes the number, so it would have an open dot.
a solid dot is , if less tha or equal to, or grearter than or just greater than and less than.
If the inequality includes 'or equal' then use a solid dot [the value is included]. If it doesn't use 'or equal' then use the open dot.
Thin of the number line with a solid dot on the number -4. Everything to the left of your dot satisfies real numbers less than or equal to 4. The set it infinite, of course. In set builder notation, {x: x< or = 4}
A line which has one end, but stretches off to infinity is called a ray. If we want to show an interval such as [2,infinity) which means all the numbers between two an infinity including two, we put a close dot at two and draw a ray going to the right. Similarly for (negative infinity, 2] we draw the closed dot at 2 but this time the ray goes to the left. Now if we draw an open circle, or a the out line of a dot this mean the interval (2,infinity) where we are considering all the numbers very close to two but not two itself This is an open half line and it represents an open interval.
It is open.

Closed. Open means it does not equal to...

Yes. DOT 4 has a higher boiling point than DOT 3, and it is less hygroscopic (less affinity for moisture). Beware of DOT 5, however, because it is not compatible with other brake fluids.
A number line is used to draw the graph of the inequality. The graph of an inequality consists of the graphs of all its solutions.If you graph x < 5 on a number line, the solution is all real numbers to the left of 5. Use an open dot at 5, to indicate that 5 is not a solution.If you graph x > 5, the solution is all real numbers to the right of 5. Use an open dot at 5 to indicate that 5 is not a solution.If you graph x = 5, the solution is all real numbers to the right of 5, included 5. Use a closed dot at 5 to indicate that 5 is a solution.Inequalities that have the same solution set are called equivalent inequalities. Solving an inequality is a process of writing equivalent inequalities until you isolate the variable. To do this, you apply the addition, subtraction, multiplication, division and transitive properties.Examples:x + 9 -6 - 15-3x > -21 divide each side of the inequality by -3, and reverse the order of the inequality (that is, change the symbol of the inequality) ;x -4 and x > 4 the word and signals a conjunction.The solutions are all numbers that are solutions of both inequalities.Use an open dot at -4 and another open dot at 4. All numbers greater than -4 and less than 4 are solutions.x < -3 or x > 5 the word or signals a disjunction.The solutions are all numbers that are solutions of either inequality.Use an open dot at -3 and another open dot at 5. All numbers less than -3 and greater than 5 are solutions.Examples:-7 < 4 - x 1All numbers less than -0.4 and greater than 1 are solutions. Use an open dot at -0.4 and another open dot at 1.

open dot means < or > but not equal to.
Stuck pixels are a fault that can be found on LCD televisions. The liquid crystal shutters normally open and close to pass varying amount of light through the panel. Every shutter should operate independently and change from fully open to fully closed. A stuck pixel is the result of a shutter that is stuck in an open or closed position. If it is open, a bright red, green or blue dot will be seen. If it closed, then it will show up on lighter images as a dark colored dot. Stuck pixels are very rare in the latest screens although they are still found from time to time.
