How does solving linear inequality differ from solving linear equation?
Linear inequalities are equations, but instead of an equal sign, it has either a greater than, greater than or equal to, less than, or a less than or equal to sign. Both can be graphed. Solving linear equations mainly differs from solving linear inequalities in the form of the solution. 1. Linear equation. For each linear equation in x, there is only one value of x (solution) that makes the equation true. The equation: x - 3 = 7 has one solution, that is x = 10. The equation: 3x + 4 = 13 has one solution that is x = 3. 2. Linear inequality. On the contrary, a linear inequality has an infinity of solutions, meaning there is an infinity of value of x that make the inequality true. All these x values constitute the "solution set" of the inequality. The answers of a linear inequality are expressed in the form of intervals. The linear inequality x + 5 < 9 has as solution: x < 4. The solution set of this inequality is the interval (-infinity, 4) The inequality 4x - 3 > 5 has as solution x > 2. The solution set is the interval (2, +infinity). The intervals can be open, closed, and half closed. The open interval (1, 4) ; the 2 endpoints 1 and 4 are not included in the solution set. The closed interval [-2, 5] ; the 2 end points -2 and 5 are included. The half-closed interval [3, +infinity) ; the end point 3 is included.
What is the solution for 3x greater than or equal to 12?
To solve the inequality 3x ≥ 12, you need to isolate x. First, divide both sides by 3 to get x ≥ 4. This means that any value of x that is greater than or equal to 4 satisfies the inequality. In interval notation, the solution is [4, ∞).
What isthe inequality 3(x-1)?
4
When would an absolute value inequality result in one interval as the solution set?
This typically happens when the absolute value is less than something. Here is a simple example:| x | < 3 This results in all numbers between -3 and 3.
Is 2 a solution to the inequality x 3?
Yes, It is a solution (a+)
Which expression the inequality x - 2 in interval notation?
x - 2 is not a inequality and so the question does not make any sense.
What is the interval set notation of -7 -3?
-4

What are at least five inequality solutions to x-3?
x - 3 is not an inequality.

Why is it usually only necessary to test one point when graphing an inequality?
One point in each interval. An entire interval, between two critical points, either fulfills, or doesn't fulfill, the inequality.For example, (x-3)(x+5) > 0; the corresponding equality is (x-3)(x+5) = 0, with the two critical points x = 3 and x = -5. The intervals that must be checked are x < -5, x between -5 and 3, and x > 3.
How do you convert a interval notation into a inequality?
[a, b] : a ≤ x ≤ b [a, b) : a ≤ x < b (a, b] : a < x ≤ b (a, b) : a < x < b

Is 3 a solution to the inequality x 3?
No, it is not a solution.
Solve the inequality 3 -2 x 7.?
The above is not an inequality as stated.
How can you tell whether an absolute value inequality is equivalent to a compound inequality with the word and or to a compound inequality with the word or?
Good question.Think about lxl > 3: x can be >3 or goes with or. < goes with and.
Define solution of a linear inequality in two variable?
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5
