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

What is the system of equations and enter the solution as an ordered pair 4x 7y equals 47 5x-4y equals -5?

Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5


What are the solutions to the simultaneous equations of 2x plus y equals 5 and x squared minus y squared equals 3?

Merge the equations together and form a quadratic equation in terms of x:- 3x2-20x+28 = 0 (3x-14)(x-2) = 0 x = 14/3 or x = 2 So when x = 14/3 then y = -13/3 and when x = 2 then y = 1

Simultaneous equations.


How many solutions do the following equations have in common 8y equals -75x - 22 and 75x equals -8y plus 22?

I notice that the ratio of the y-coefficient to the x-coefficient is the same in both equations. I think that's enough to tell me that their graphs are parallel. So they don't intersect, and viewed as a pair of simultaneous equations, they have no solution.

0 = 0 is an identity and not an equation. Equations have solutions, identities do not.


What are the solutions to the simultaneous equations of x over 3 -y over 4 equals 0 and x over 2 plus 3y over 10 equals 27 over 5?

Simultaneous equations: x/3 -y/4 = 0 and x/2 +3y/10 = 27/5 Multiply all terms in the 1st by 12 and in the 2nd equation by 10 So: 4x -3y = 0 and 5x +3y = 54 Add both equations together: 9x = 54 => x = 6 Solutions by substitution: x = 6 and y = 8


What are the values called at which the equation equals zero?

They are called the solutions or roots of the equations.

It works out that the solutions are: x = 3 and y = 2


What is y equals 2x-1 and y equals 2x plus 1?

They are two equations in two unknown variables (x and y), which are inconsistent. That is to say, there is no simultaneous solution. An alternative approach is to say that they are the equations of two lines in the Cartesian plane. The lines are parallel and so they do not meet indicating that there is no simultaneous solution.
