To solve an inequality on a number line, first isolate the variable on one side of the inequality. Then, determine the critical points by setting the inequality to equal zero and solving for the variable. Next, plot these points on the number line, and use test intervals to determine where the inequality holds true. Finally, shade the appropriate region of the number line and use open or closed circles to indicate whether the endpoints are included or not, based on whether the inequality is strict (>, <) or inclusive (≥, ≤).

How you solve Inequality?
To solve an inequality, first isolate the variable on one side of the inequality sign, similar to how you would solve an equation. This involves performing the same operations on both sides, such as adding, subtracting, multiplying, or dividing, while remembering that if you multiply or divide by a negative number, you must reverse the inequality sign. After isolating the variable, express the solution in interval notation or graph it on a number line to represent all possible values that satisfy the inequality.
How do you write and solve an absolute value inequaolity?
To write and solve an absolute value inequality, start by expressing the inequality in the form |x| < a or |x| > a, where a is a positive number. For |x| < a, split it into two inequalities: -a < x < a. For |x| > a, split it into two separate inequalities: x < -a or x > a. Finally, solve each inequality to find the solution set and represent it using interval notation or a number line.
How to solve and graph and inequality?
To solve an inequality, isolate the variable on one side by performing inverse operations, similar to solving an equation. For example, if you have (2x + 3 < 7), subtract 3 from both sides and then divide by 2 to find (x < 2). To graph the inequality on a number line, use an open circle for "<" or ">" to indicate that the endpoint is not included, or a closed circle for "≤" or "≥" to indicate inclusion. Shade the region of the number line that satisfies the inequality, extending in the appropriate direction.

How do you solve inequalities on a number line?
To solve inequalities on a number line, first isolate the variable on one side of the inequality. Then, determine the solution set, which may involve finding critical points where the inequality changes from true to false. Plot these points on the number line, using open circles for strict inequalities (e.g., < or >) and closed circles for inclusive inequalities (e.g., ≤ or ≥). Finally, shade the appropriate region that represents all possible solutions.

How do you solve a two step inequality?
To solve a two-step inequality, first isolate the variable by performing the same operations on both sides of the inequality. Start by adding or subtracting a constant term from both sides, followed by multiplying or dividing by a non-zero coefficient. Remember to reverse the inequality sign if you multiply or divide by a negative number. Finally, express the solution in interval notation or graph it on a number line.

How do you solve an inequality when using the distributive property?
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
How do you solve a linear equation of an inequality or equation?
To solve a linear equation or inequality, first isolate the variable on one side of the equation or inequality. For an equation, use operations like addition, subtraction, multiplication, or division to simplify until the variable is alone (e.g., (ax + b = c) becomes (x = (c-b)/a)). For an inequality, follow similar steps but remember to reverse the inequality sign if you multiply or divide by a negative number. Finally, express the solution in interval notation or as a graph on a number line, depending on the context.
How do you solve multi-step inequality word problems?
To solve multi-step inequality word problems, start by carefully reading the problem to identify the variable, the inequality relationship, and any constants involved. Next, translate the written expressions into mathematical inequalities. Then, isolate the variable by performing inverse operations, ensuring to reverse the inequality sign when multiplying or dividing by a negative number. Finally, express the solution in interval notation or graph it on a number line, as needed, to convey the range of values that satisfy the inequality.
