The Power of x = -4 in Mathematical Equations and Graphing

x = -4

If x = -4, it means that the variable x is equal to -4

If x = -4, it means that the variable x is equal to -4. In other words, -4 is the value assigned to x.

This information can be useful for various mathematical operations. For example:

1. Algebraic equations: You can substitute x = -4 into equations to find the value of other variables. For instance, if you have the equation 2x + 3 = 5, you would replace x with -4: 2(-4) + 3 = 5. Simplifying, you get -8 + 3 = 5, and further, -5 = 5, which is a false statement.

2. Graphing: On a Cartesian coordinate system, where the x-axis represents horizontal values, you would plot the point (-4, y), where y can be any value, as it is not specified. This point would lie exactly 4 units to the left of the origin (0, 0) on the x-axis.

3. Arithmetic operations: You can perform various arithmetic operations involving x = -4. For instance, if you have the expression 2x^2 – 3x + 1, you would substitute x with -4: 2(-4)^2 – 3(-4) + 1. Evaluating this expression, you get 2(16) + 12 + 1 = 32 + 12 + 1 = 45.

Remember, whenever you have a specific value assigned to a variable (in this case, x = -4), you can use it in mathematical calculations to solve equations, graph points, or perform arithmetic operations involving that variable.
