An equality defines a specific point (or points). An inequality can define an interval.
-4
any number that makes the inequality true
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
Substitute the number in place of the variable, and see whether the inequality is then a true statement.
Always.
The multiplication property of equality states that if you multiply both sides of an equation by the same non-zero number, the two sides remain equal. In contrast, the multiplication property of inequality states that if you multiply both sides of an inequality by a positive number, the inequality remains unchanged, but if you multiply by a negative number, the inequality sign must be flipped. Thus, while equality preserves its form, inequality requires careful handling based on the sign of the multiplier.
All I know is a number sentence. It is one with an operation, (+-*/) and an inequality/equality.
-1 is -1. It can be neither true nor false as there is no equality or inequality sign.
The word "is" implies equality - an equation. An equality would be expressed different, for example, "is more than", "is at least", etc.
In mathematics, the solution of an inequality refers to the set of values that satisfy the inequality condition. For example, in the inequality (x > 3), any number greater than 3 is considered a solution. These solutions can often be represented on a number line or in interval notation, illustrating all possible values that fulfill the inequality. Essentially, it identifies the range of values for which the inequality holds true.
You solve an inequality in the same way as you would solve an equality (equation). The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign. Thus, if you have -3x < 9 to find x, you need to divide by -3. That is a negative number so -3x/(-3) > 9/(-3) reverse inequality x > -3
There isn't an equality as the phrase is an inequality. Mathematically, it would be written: oranges_sold > 25
Yes, you can divide both sides of an equation by a negative number, but it is important to remember that this action will reverse the inequality if the equation involves one. For example, if you have an inequality like ( x > y ) and you divide both sides by a negative number, the inequality changes to ( x < y ). In the case of an equation, however, the equality remains valid.

An interval on the number scale is a set of numbers between two end-point. Thus the closed interval [a, b] comprises all number between a and b as well as the two end points. An interval is open if neither end point is included, and semi-open (or semi-closed) if one end in included and the other is not.
The question contains an expression, not an equality or inequality. An expression cannot be true (or untrue).
Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g. 10>4. If you multiply both sides by -2, you need to change the > into a <, so -20<-8
