What are the four types of inequalities math?

Inequalities – GMAT Math Study Guide

• Greater Than (>)
• Less Than (<)
• Greater Than or Equal to (>)
• Less Than or Equal to (<)
• Not Equal to (≠)

What are the inequality symbols?

These inequality symbols are: less than (<), greater than (>), less than or equal (≤), greater than or equal (≥) and the not equal symbol (≠). Inequalities are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable.

How do you calculate an inequality?

Plug your slope and a point into the formula y = mx + B, in which “m” is the slope, (x, y) is a point on the line and “b” is the y-intercept, to find the equation governing the inequality line. Plugging in (0, 0), you obtain 0 = 0 + b, so b = 0. Rewriting the equation, you obtain y = x/2.

What does inequality mean in math?

Inequality. (mathematics), a relation between two numbers or quantities indicating which of them is greater or smaller. An inequality is denoted by the symbol <, which is drawn pointed toward the smaller number. Thus, 2 > 1 and 1 < 2 state the same thing, namely, 2 is greater than 1 and 1 is less than 2.

How do I write an inequality equation?

Solution Step 1: Highlight the important information in this problem. Step 2: Identify your variable. Step 3: Write your inequality. Step 4: Solve the inequality. Step 5: Justify (prove your answer mathematically). Step 1: Highlight the important information in this problem. Step 2: Identify your variable. Step 3: Write the inequality.

What is example of solving inequalities?

“Solving” an inequality means finding all of its solutions. A “solution” of an inequality is a number which when substituted for the variable makes the inequality a true statement. Here is an example: Consider the inequality When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x =8 is a solution of the inequality.
