Can you have a negative X in algebra?

No, it does not have to be negative: If the original value of x was negative, then –x, the opposite-signed version of x, would have to be positive. For instance, if I start with x = –3, then –x = –(–3) = +3, which is positive.

What is the coefficient of negative X?

Graphing. Negative coefficients can mean a lot when it comes to graphing a function. For linear functions, a negative coefficient in front of the x means the m value or slope is negative. A negative slope will change how the line is graphed.

What is example of value in math?

Mathematics: a number, or the result of a calculation. Example: 3 × 4 gives the value of 12. Money: how much something is worth. Example: the value of this coin is one dollar.

Variables can be negative or positive in nature. Learn to manipulate variables in a variety of ways if you take a high school or college algebra or calculus course. ... A negative variable times a positive variable will produce a negative product. For example, -x * y = -xy.

What is the absolute value of negative 3?

Negative 3 is three units away from zero, which means the absolute value of -3 is 3. This gives us 1 minus 3, which equals -2. Since absolute value is a calculation of a number's distance from zero, an absolute value expression such as the absolute value of 3 can be written as the absolute value of 3-0.

What is the absolute value of 7?

|7| = 7 means the absolute value of 7 is 7.
