## Do you have to cite equations?

Please note that tables, figures, and equations should always be introduced within the body of the paper before you show the actual table / figure / equation. If the data, or the figure itself, comes from an outside source, you should cite that source when you introduce the table / figure / equation.

## How do you describe an equation?

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.

How do you describe an equation in words?

In chemistry, a word equation is a chemical reaction expressed in words rather than chemical formulas. The words “and” or “plus” mean one chemical and another are both reactants or products. The phrase “is reacted with” indicates the chemicals are reactants.

### Can Word solve equations?

However, if you’re working in Microsoft Word, you can calculate simple equations typed into your document using Word’s not-so-obvious Calculate command. To use the Calculate command, we need to add it to the Quick Access Toolbar.

### How does writing an equation help solve a problem?

It tells us that two expressions mean the same thing, or represent the same number. An equation can contain variables and constants. Using equations, we can express math facts in short, easy-to-remember forms and solve problems quickly. Here are several examples of equations.

#### How do you write an inequality with two variables?

To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line.

#### What is the solution of an inequality?

A “solution” of an inequality is a number which when substituted for the variable makes the inequality a true statement. Adding/subtracting the same number on both sides. Example: The inequality x-2>5 has the same solutions as the inequality x > 7.

What are the rules of inequalities?

If you add the same number to both sides of an inequality, the inequality remains true. If you subtract the same number from both sides of the inequality, the inequality remains true. If you multiply or divide both sides of an inequality by the same positive number, the inequality remains true.

How do you make an inequality true?

To determine whether an inequality is true or false for a given value of a variable, plug in the value for the variable. If an inequality is true for a given value, we say that it holds for that value. Example 1. Is 5x + 3≤9 true for x = 1 ?

## What is the golden rule of inequalities?

I must have still been half-asleep when I typed up these notes because I called it The Golden Rule of Inequalities: Whenever you multiply or divide both sides of an inequality by a negative number, you must flip the inequality symbol.

## How many solutions does an inequality have?

Like systems of equations, system of inequalities can have zero, one, or infinite solutions. If the set of solutions includes any shaded area, then there are indeed an infinite number of solutions.

What is the difference between the solution of an equation and the solution of an inequality?

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses. !!!!!
