What is the meaning of the prefix-sub

Write a compound inequality to represent the sentence below:
A Quantity x is either less than 10 or greater than 20.

An inequality with a linear function included is referred to as a linear inequality. When the word "and" connects two inequalities, the solution takes place when both inequalities hold true at the same moment. The solution, however, only applies when one of the two inequalities is true when the two are connected by the word "or." The combination or union of the two separate solutions is the solution. When two simple inequalities are combined using either "AND" or "OR," the result is a compound inequality.
One of the two claims is proven to be true by the compound inequality with "AND." If the answers to the separate statements of the compound inequality overlap. While "Or" means that the entire compound sentence is true as long as either of the two statements is true. The solution sets for the various statements are united to form this concept.

Write a compound inequality to represent the sentence below: A Quantity x is at least 10 and at most 20.

The value for area A of each figure is given. Write and solve a compound inequality for the value of x in each figure.
9 ≤ A ≤ 12

Here is a list of some key points to remember when studying triangle inequality:
• The Triangle Inequality theorem states that the sum of any two sides of a triangle must be greater than the sum of the third side.
• In a triangle, two arcs will intersect if the sum of their radii is greater than the distance between their centres.
• If the sum of any two sides of a triangle is greater than the third, the difference of any two sides will be less than the third.

The value for area A of each figure is given. Write and solve a compound inequality for the value of x in each figure. 35 ≥ A ≥ 25

Let a and b be real numbers. If a > b, how is the graph of x > a and x > b different from the graph of x > a or x > b

Solve each compound inequality and graph the solution

Suppose that a < b. Select from the symbols <, >, ≥, ≤ as well as the words and & or to complete the compound inequality below so that its solution is all real numbers
x     a      X      b

The compound inequality solution is x > 3 or x ≤ 4 and is the set of all real numbers. As shown in the example below, one needs to solve one or more inequalities before determining the solution to the compound inequality. Solve each inequality by removing the variable.
An inequality with all real numbers as solutions is simple to solve or identify. Here is an example.
Example
Solve x - x > -1
x - x > -1
Because x - x = 0, we get 0 > -1.
This inequality holds because 0 is always greater than -1. As a result, all real numbers are solutions.

Describe and correct the error a student made graphing the compound inequality x ≥ 2 and x > 4

A graph of a compound inequality with a "or" shows how the graphs of the individual inequalities are combined. If a number solves any of the inequalities, then it is a solution to the compound inequality. A compound inequality results from the combination of two simple inequality problems. Steps on Graphing compound Inequalities
1. Reconcile every inequality. 6x−3<9. ...
2. Graph every response. The numbers that prove both inequalities are plotted. The final graph will display all the values—the values shaded on both of the first two graphs— true for both inequalities.
3. Use interval notation to write out the answer. [−3,2)

The compound inequality x > a and x > b is graphed below. How is the point labelled c related to a and b?

When working with inequalities, we can treat them similarly to, but not identically to, equations. We can use the addition and multiplication properties to help us solve them. The inequality symbol must be reversed when dividing or multiplying by a negative number. This question concluded that inequalities have the following properties:
A GENERAL NOTE: PROPERTIES OF INEQUALITIES
Addition Property: If a<b, then a + c < b + c.
Multiplication Property: If a < b and c > 0, then ac < b c and a<b and c < 0, then ac > bc.
These properties also apply to a ≤ b, a > b, and a ≥ b.

2x-5 > 3 and -4x+7 < -25
 

Divide a compound inequality into two individual inequalities before solving it. The solution should either be a union of sets ("or") or an intersection of sets ("and"). After that, resolve the graph and all inequalities.
Use the steps below to resolve an inequality:
Step 1: Fractions are first eliminated by multiplying all terms by the total fractions' lowest common denominator.
Step 2: Simplify the inequality by combining like terms on each side.
Step 3: Subtract or add quantities to get the unknown on one side and the numbers on the other.

The slope of line a is – 4. Line b is perpendicular to line a. The equation of line c is 3y + 12x = 6. What is the relation between line b and line c?

Nadeem plans to ride her bike between 12 mi and 15 mi. Write and solve an inequality to model how many hours Nadeem will be riding?

In this question, the time taken to ride by Nadeem is to be calculated with the help of the speed and distance formula (time = distance/speed). So, for example, to determine the time required to complete a journey, we must first know the distance and speed.
There are three different ways to write the formula. They are:
• speed = distance ÷ time
• distance = speed × time
• time = distance ÷ speed
Calculating with the time formula gives us the answer as an inequality.
