How do you decide whether a number is a solution of an inequality?
Substitute the number in place of 'x' in the inequality, and see whether the statement you have then is true.
How do you graph -6 is greater than x plus 5 as an inequality on a number graph?
The inequality -6 > x+5 can be rewritten -11 > x (by subtracting five from each side) or rather x < -11. To graph this on a number line, draw an open circle over the number -11 (if the inequality included "or equal to" the circle would be filled in). Then draw a line/arrow coming out of the circle over the number line. The line should only be drawn over the portion of the number line that makes the inequality true. For instance, choose a test point. When x is -20, the inequality is true: -20 < -11. So in this case, the arrow coming out of the open circle will point to the left, in the direction that the number line is getting smaller.
How do you know if a value is a solution for an inequality?
A number is called a "solution" for an inequality if, when you plug that number into the variable, the inequality becomes true. For example, 4 is a solution to the inequality "x + 5 < 10", because when you plug in 4 for x, you get "4 + 5 < 10", which is true. (4 plus 5 is 9, which is less than 10.) On the other hand, 6 is not a solution to the inequality "x + 5 < 10", because when you plug in 6 for x, you get "6 + 5 < 10", which is false. (6 plus 5 is 11, which isn't less than 10.)
What are linear inequalities in two variables?
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
What is the set of all numbers that make the inequality true?
It is the solution set for that particular inequality.
What is a double inequality?
A double inequality is an inequality where there are two signs, as opposed to one.Ex: an inequality could be 3x < 15A double inequality could be 3x < 15 < x + 20If you'd want to solve that double inequality, you split it into to expressions:3x < 15 and x + 20 > 15Then just solve.x < 5 and x > -5-5 < x < 5
How do you decide whether a number is a solution of an inequality?

How do tell the solution of an inequality?
Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.

How do you know if a specific point is a solution to an inequality?
substitute the numbers into the inequality and see if it is true. EX: x > y+ 3 for the point (1, 6) .... 1 > 6 + 3 is not true so this point is not a solution.
What is x over 6 plus 11 and gt20?
If you mean: x/6 +11 = 20 then the value of x is 54 Check: 54/6 +11 = 20
Write an Inequality for this problem situation below. Solve each inequality. What is the width of a rectangle whose length is 4feet and perimeter is at most 20feet?
Let the width be x:- 2(x+4) = 20 2x+8 = 20 2x = 20-8 2x = 12 x = 6 So the width is 6 feet

What is the inequality of x - 4 6?
What is the inequality of: x - 4 < 6
What value of the variable x makes the inequality of x is greater than 4 true?
Any value of x that is more than 4, for example 4.000000000000001
