How can you tell when an equation has a solution of all real numbers?
Definition: An equation is a statement that asserts that two mathematical expression are equal in value. When this is true for all values of the variables involved then it is called an identity, for example 2(x - 5) = 2x - 10. If you work at one side (or in both sides separately), you will find the same expression in both side., such that: 2x - 10 = 2x - 10 this is an identity, so that the solution of the equation is the set of all real numbers.
What can the discriminant tell you about a quadratic equation?
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
How can you tell if an equation is a linear relationship?
If it is in a y=mx+b format. Also, if there is a slope and a constant in the equation.
What does solving the equation for a line tell us?
A line is represented by an equation. Each solution of the equation is a point on the line, and each point on the line is a solution to the equation. So the line is just the graph of the solution set of the equation.
Tell what it means to solve an equation?
To find how big your stick is.
When you use the substitution method how can you tell that a has an infinite number of solutions?
If the process of substituting leads to an identity rather than an equation then the system has infinitely many solutions.
What is a self consistent equation?
The opposite of an inconsistent oneI'm not trying to be a wise guy. It's just easier to give you an example of an inconsistent equation and then tell you that a "self-consistent" one is the opposite. Here's an example of an inconsistent equation:3x/(x-2) = (4x2 - 8x)/(x2 - 4x + 4)On its face, it looks perfectly fine. It is not immediately obvious that you can't solve for x and get a meaningful result. But if you take the time to factor the numerator and denominator of the righthand part of the equation, you'll start to see the problem. If you continue and try to solve for x using normal algebraic techniques, you will get the impossible result: 3 = 4.That result shows that your starting equation is internally inconsistent; that is, it is not consistent with itself.Solution:3x/(x-2) = (4x2 - 8x)/(x2 - 4x + 4)3x/(x-2) = 4x(x - 2)/(x - 2)23x = 4x!!Don't you like x=0?As a solution to your full-consistent equation?Beside that, your definition of self-consistent equation is right. On the contrary the specific example is not.It is worth noting that often "self-consistent equation" is a misuse for "self-consistency equation", namely an equation whose role is to guarantee the self consistency of a theory (model, whatever). If the equation is satisfied then the theory is self-consistent.Literally a "self-consistent equation" is a meaningful one.
Is 4y minus 8x equals negative 16 consistent or inconsistent?
It's not possible to tell without another equation that supposedly represents the same line; it's only when you have two or more "comparisons" that you can establish consistency or inconsistencies.
Which type of reasoning is based on conditional statements?
If I knew, I would tell you. (This was an example.)
What does conditional mean in Excel?
Requirements that must be met before the action can take place.E.g Conditional Formatting is where you tell the spreadsheet to format a cell IF it meets the condition set.
Can you tell how a quadratic equation can become linear equation?
You can easily tell by substituting 0 for a.
Why can't you square each side of the equation when verifying a trigonometric identity?
When we work to verify an identity, we work separately to both sides, and to see in the end if we have an equality. If we square both sides, that means that we assume that the equality exist, so we do not need to verify it. It looks for a solution, which will tell us if the statement is sometimes, always (identity), or never true.
