A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

By elimination: x = 3 and y = 0

Can You Solve 2x plus 3y equals 18 and 2x-3y equals -6 Using The Elimination Method?

Yes and it works out that x = 3 and y = 4

Can quadratic systems be solved using elimination and substitution?

You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.

How do you solve using elimination method 2x-y equals -2?


How do you solve 0.2x plus 4y equals -1 by using Elimination?

You cannot solve one linear equation in two variables. You need two equations that are independent.

Simultaneous equations can be solved using the elimination method.

4x-7y equals 13 -2x plus 7y equals -3?

One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.

What is 2y-2x-8 3y-18-3x using elimination method?

There is no answer because you can't find the value of x and y if you do not have and equals sign.

What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?

There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

Solve this equation using addition method -8x plus 3y equals -5 and 8x subtract 2y equals 6?

x=1, y=1

Solve the system using elimination 3x -9y equals 3?

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.

How do you decide whether to use elimination or subsitution to solve a three-variable system?

There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.

Can you solve the system using elimination 3x plus 9y equals 3?

No. Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.

What is 3x plus 2y 18 x-3y -5 using the elimination method?

Using the elimination method, 3x + (2y) times 18x - 3y - 5 gives the result of 36xy + 3x - 3y - 5.

When is it best to solve a systems of linear equations using elimination?

Elimination is particularly easy when one of the coefficients is one, or the equation can be divided by a number to reduce a coefficient to one. This makes substitution and elimination more trivial.

Solve 5x 2y5 and 3x-4y-23 using elimination?

5x - 4y ≥ -203x - 2y ≤ -8y ≥ -3

What is graphical method?

The graphical method is a method used to solve algebraical problems by using graphs.

How would you solve this using elimination 5x-10y equals 15 3x plus 7y equals 31?

You could multiply the first equation by 3 and the second by -5 and eliminate the x... OR you could multiply the first equation by 7 and the second by 10 and eliminate the y. Either way works.

Solve system of equation using Gauss Jordan form- When I try to solve these I find that the matrix is singular. Does that mean no solution x plus 2y-3z equals 1 y-2z equals 2 2y-4z equals 4?

The matrix is singular because the last equation is the same as the second equation (simply multiplying every term in an equation by the same number (in this case, 2) does not produce an equation with new information). for example 1) 3x=3y 2) 2x=2y has no useful solution beyond the information from 1) that x=y You would get a singular matrix for this. The Gauss-Jordan method will not solve equations which cannot be solved by the old "elimination method".
