Best Answer

To evaluate means to find the value. Substitute the values of the variables and calculate the value. [You may need to solve for the values of the variables first.]

How do you evaluate linear equations involving addition and subtraction?

You add or subtract, as required by the equation!


Why does a CPU evaluate the expression 'a' equals 'a' as true?

CPUs, when given mathematical equations, apply the laws of mathematics to those equations. The equation a = a is true by the reflexive property of equality.

How did you find each product of quadratic equations?

You substitute the value of the variable into the quadratic equation and evaluate the expression.


What does it mean for a coordinate pair to be a solution to a system of equations?

It means that if you replace one variable with one of the numbers, and the other variable with the other numbers, and then evaluate the expressions on each side of the equations, the equalities will be true.


How do you check a solution to a system of equations?

Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.


What are the different Types of mathematical equations?

Algebraic equations, trigenometric equations, linear equations, geometric equations, partial differential equations, differential equations, integrals to name a few.


What is the equation and variable labels for free falling water?

There are different formulas/equations used for a free falling object. In order to evaluate the distance D travelled by an object for a time T, we can use d=1/2 gt2. Likewise, to evaluate time taken for an object to fall a specific distance, we can use t=?2d/g.


What is the classification of a system of equations?

The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.

What are equivalant equations?

Equivalent equations are equations that have the same solution set.


Why is it better to solve quadratic equations in the complex number system rather than in the real number system?

It is not always better.Although quadratic equations always have solutions in the complex system, complex solutions might not always make any sense. In such circumstances, sticking to the real number system makes more sense that trying to evaluate an impossible solution in the complex field.
