What else can I help you with?
When using the addition or substitution method how can you tell whether a system of linear equations has infinitely many solutions and what is the relationship between the graphs of the two equation?
If it has infinite number of solutions that means that any ordered pair put into the system will make it true. I believe the relationship of the graphs question your asking is that tooth equations will probably be the same line
What is the extraneous solution to w equals sqrt 7w?
An "extraneous solution" is not a characteristic of an equation, but has to do with the methods used to solve it. Typically, if you square both sides of the equation, and solve the resulting equation, you might get additional solutions that are not part of the original equation. Just do this, and check each of the solutions, whether it satisfies the original equation. If one of them doesn't, it is an "extraneous" solution introduced by the squaring.
How do you judge whether an equation has solutions by looking at it in standard form?
If you're talking about two linear equations, make sure they are not parallel. If you're talking about quadratics, make sure that b2-4ac is not negative.
Determine whether each equation is a linear equation If so write the equation in standard form and determine the x-intercept and y-intercept 1 8x - 3y 6-4x 2 5 - 2y 3x 3 5x - 2y 7?
Without any equality signs the expressions given can't be considered to be equations
How can you solve a system of equations?
The answer depends on whether they are linear, non-linear, differential or other types of equations.
What is the ordered pair for the equation y-3x-8 and y2x 2?
Without any equality sign and not knowing whether or not 2 is + or they cannot be classed as equations
Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
Determine if the ordered pair y3x 5 yx 9 211 isa solution to the system of equations?
Tell whether the ordered pair (5, -5) is a solution of the system
When using the addition or substitution method how can you tell whether a system of linear equations has infinitely many solutions and what is the relationship between the graphs of the two equation?
If it has infinite number of solutions that means that any ordered pair put into the system will make it true. I believe the relationship of the graphs question your asking is that tooth equations will probably be the same line
How do you find the value of each variable?
There are various methods which depend on the nature of the equation(s) and whether or not the equations can be solved analytically.
How do I write an equation in standard form with integer coefficients?
The answer will depend on the form of the equation. Whether it is an equation in one or more variables, whether it is linear or polynomial, there are different standard forms for exponential equations.
How can you determine whether a point is a solution to system of equations?
You substitute the coordinates of the point in the equation. If the result is true then the point is a solution and if it is false it is not a solution.

Why do you have to check the solutions when you have to solve radical equations?
Checking your solution in the original equation is always a good idea,simply to determine whether or not you made a mistake.If your solution doesn't make the original equation true, then it's wrong.
6x 7y equals 96?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution. Furthermore, it is not clear whether there is meant to be a symbol between 6x and 7y. Well the guy failed at asking a question but im sure he means 6x+7y=96 Whoever can solve that would be nice. Answer should be in a ordered pair. * * * If s/he means 6x + 7y = 96, then this equation, of a line in two dimensional space is the set of solutions. Each and every one of the infinite number of points on that line is a solution.
Is 3x - 3y 21 and 5x 4y 24 a solution?
To determine if (3x - 3y = 21) and (5x + 4y = 24) have a solution, we can solve the system of equations. Rearranging the first equation gives (x - y = 7) or (x = y + 7). Substituting this into the second equation allows us to find values for (x) and (y). Solving the resulting equation will reveal whether there are specific values that satisfy both equations simultaneously.
How do you judge whether an equation has solutions by looking at it in standard form?
If you're talking about two linear equations, make sure they are not parallel. If you're talking about quadratics, make sure that b2-4ac is not negative.
