What happens if you have a negative variable
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 negativeproduct. 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 solve system of equations?
- 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?
- 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 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 |
