## What is a justification sentence?

Definition of Justification. an explanation of how something is reasonable or correct. Examples of Justification in a sentence. 1. Phillip was fired when he was unable to offer justification for his repeated tardiness to work.

### How do you write justify in a sentence?

- How can they justify paying such huge salaries?
- No argument can justify a war.
- He tried to justify his absence with lame excuses.
- Ministers must appear before parliament and justify their actions.
- He decided there was insufficient evidence to justify criminal proceedings.http://sentencedict.com.

#### What do you write in a justification study?

The best way to write this is to introduce the current literature in the background/Introduction section and then highlight the gaps in the literature that have not been addressed or are yet to be understood. This will help set up the need for the current study and thus justify the need for this research.

**How do you teach students to justify their answers?**

To support students to justify their solutions, the teacher can:

- have a class discussion about what it means to justify a solution.
- provide a problem to students and have them solve it, recording their justifications.
- ask students to work in pairs to justify their solutions.

**What is to solve an equation?**

In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.

## How do I simplify an expression?

To simplify any algebraic expression, the following are the basic rules and steps:

- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.

### Why do we solve equations?

Even if they can, it is often simpler and faster to use a computational method to find a numerical solution. The real power of equations is that they provide a very precise way to describe various features of the world. (That is why a solution to an equation can be useful, when one can be found. )

#### What is a problem with no solution?

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.

**How do you know if there is no solution?**

The coefficients are the numbers alongside the variables. The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

**How can you tell if an equation has infinite solutions?**

If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.

## How do you know if a system has infinite solutions?

If a system has infinitely many solutions, then the lines overlap at every point. In other words, they’re the same exact line! This means that any point on the line is a solution to the system. Thus, the system of equations above has infinitely many solutions.

### Do parallel lines have infinite solutions?

When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions. Some special terms are sometimes used to describe these kinds of systems.

#### What happens when a system of equations cancels out?

1 Expert Answer If both x and y are going to cancel out, then you have either no solution or infinitely many solutions. If the constant on the right are going to cancel out (same number with opposite signs) then there are infinitely many solutions (same line).
