# What happens if you have a negative variable

**Negative**Coefficients are those that attach to

**variables**. negative co-efficients

**terms can be**combined, if they are similar terms. The graph's nature can be altered completely when graphing functions have negative coefficients.

How can you eliminate a negative number?

Two negative signs can cancel each other. If you have a even number or zero **negative** sign, the answer will be positive. If there are more negative signs than positive, the answer is negative.

Second, is it possible to have a negative variable. Variables can either be positive or negative in nature. A negative variable multiplied by a positive variables will create a **negative**product. For example, -x * y = -xy. If the variable is the exact same, add an exponent of 2.

How can you make a negative situation into a positive?

Simply multiply a negative number with -1 to get a positive number. Below is a list of cells that contain **negative** number. To convert them to positive, you will need to enter cell B2 the formula and drag it to the end.

Is the variance possible to be negative?

Negative variance means you have made an error. This is because it is the average squared deviation of the mean. Negative variance can't be calculated by adding up non-negative numbers.

### How do you make an equation positive?

**positive**then multiply by 1.

### What are the rules for solving inequalities?

**solving**an

**inequality**: • you can add the same quantity to each side • you can subtract the same quantity from each side • you can multiply or divide each side by the same positive quantity If you multiply or divide each side by a negative quantity, the

**inequality**symbol must be reversed. So the

**solution**is x > −1.

### Do you flip inequality sign when dividing?

**dividing**an

**inequality**is the same as multiplying or

**dividing**an equation. Whenever

**you**multiply or

**divide**an

**inequality**by a negative number,

**you**must

**flip**the

**inequality sign**.

### What is an inequality in algebra?

**inequality**says that two values are not equal. a ≠ b says that a is not equal to b. There are other special symbols that show in what way things are not equal. a < b says that a is less than b. a > b says that a is greater than b.

### Why does dividing by a negative change an inequality?

**Dividing by a negative**number is the same as

**dividing**by a positive number and then multiplying by −1. But, multiplying by −1 is the same as switching the signs of the numbers on both sides of the

**inequality**, which reverses the

**inequality**: a<b?−a>−b.

### What are coefficients?

**coefficient**is a constant term related to the properties of a product. In the equation that measures friction, for example, the number that always stays the same is the

**coefficient**. In algebra, the

**coefficient**is the number that you multiply a variable by, like the 4 in 4x=y.

### How do you solve system of equations?

**Here's how it goes:**

- Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for y:
- Step 2: Substitute that equation into the other equation, and solve for x.
- Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

### How do you solve inequalities graphically?

**How to Graph a Linear Inequality**

- Rearrange the equation so "y" is on the left and everything else on the right.
- Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

### What is a one step inequality?

**steps**are like solving

**one**-

**step**equations involving multiplication or division EXCEPT for the

**inequality**sign. Let's look at what happens to the

**inequality**when you multiply or divide each side by the same number. When you multiply by a positive number, leave the

**inequality**sign as it is!

### Why are 2 negatives multiplied a positive?

**multiply**a

**negative**by a

**negative**you get a

**positive**, because the

**two negative**signs are cancelled out.

### Why do two negatives make a positive?

**two negatives**is a

**positive**is therefore related to the fact that the inverse of the inverse of a

**positive**number is that

**positive**number back again.

### Do two negatives equal a positive?

**two negative**signs, one turns over, and they add together to make a

**positive**. If you have a

**positive**and a

**negative**, there is one dash left over, and the answer is

**negative**.

### What are the rules for negative numbers?

Rule | Example | |
---|---|---|

+(+) | Two like signs become a positive sign | 3+(+2) = 3 + 2 = 5 |

−(−) | 6−(−3) = 6 + 3 = 9 | |

+(−) | Two unlike signs become a negative sign | 7+(−2) = 7 − 2 = 5 |

−(+) | 8−(+2) = 8 − 2 = 6 |

### What is a negative divided by positive?

**positive**number

**divided**by a

**negative**number equals a

**negative**number. When you

**divide**a

**negative**number by a

**positive**number, your answer is a

**negative**number. As with multiplication, it doesn't matter which order the

**positive**and

**negative**numbers are in, the answer is always a

**negative**number.

### What are the rules for adding and subtracting positive and negative numbers?

**adding positive numbers**, count to the right. When

**adding negative numbers**, count to the left. When

**subtracting positive numbers**, count to the left. When

**subtracting negative numbers**, count to the right.

### What does a negative and a positive equal in addition?

**positive**numbers are multiplied together or divided, the answer is

**positive**. If two

**negative**numbers are multiplied together or divided, the answer is

**positive**. If a

**positive**and a

**negative**number are multiplied or divided, the answer is

**negative**.

### How does a negative times a negative equal a positive?

**negative**number and figure out the answer by multiplying. This is an illustration of a

**negative times a negative**resulting in a

**positive**. If one thinks of multiplication as grouping, then we have made a

**positive**group by taking away a

**negative**number twelve

**times**.
