First degree equations ad inequalities in one variable are known as linear equations or linear inequalities. The one variable part means they have only one dimension. For example x=3 is the point 3 on the number line. If we write x>3 then it is all points on the number line greater than but not equal to 3.

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

Why are linear equations also called first-degree equation?

Equations can be classified according to the highest power of the variable. Since the highest power of the variable in a linear equation is one, it is also called a first-order equation.


What are the differences of linear and non-linear equation?

Linear equations have a variable only to the first degree(something to the power of 1). For example: 2x + 1 = 5 , 4y - 95 = 3y are linear equations. Non-linear equation have a variable that has a second degree or greater. For example: x2 + 3 = 19, 3x3 - 10 = 14 are non-linear equations.


What is the degree of 3x?

first degree degree is measuremed by the number of power on the variable


Example equations of linear equations?

y=3x+2 y-4x=9 These are examples of linear equations which is a first degree algebraic expression with one, two or more variables equated to a constant. So x=2 is a linear equation as is y=1 but x2 =1 is not since the variable, x , has degree 2.


Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?

Isolating a variable in one of the equations.


When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?

isolate


When you solve a system of linear equations by adding or subtracting what needs to be true about the variable terms in the equations?

I guess you mean, you want to add two equations together. The idea is to do it in such a way that one of the variables disappears from the combined equation. Here is an example:5x - y = 15 2x + 2y = 11 If you add the equations together, no variable will disappear. But if you first multiply the first equation by 2, and then add the resulting equations together, the variable "y" will disappear; this lets you advance with the solution.


What is usually the first step in solving a system of nonlinear equations by substitution?

The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.


How do you solve the system of equations when you have 4 equations with 4 unknowns?

There are several ways to do it - depending, in part, on the kind of equations. Sophisticated methods exist specifically for linear equations, among others. However, for a start, you can combine equations (1) and (2), eliminating one variable; the same for equations (2) and (3), and for equations (3) and (4) (eliminating the same variable in every case). That leaves you with 3 equations with 3 variables. Similarly, reduce the 3 equations in 3 variables, to 2 equations in 2 variables (eliminating the same variable in every case). Combine those into a single equation with 1 variable. Example for eliminating a variable: (Eq. 1) 5a + 3b - 3c + 8d = 28 (Eq. 2) 8a - 3b + 8c - 6d = 8 If you just add up the equations, you eliminate variable b. If you want to eliminate variable a, multiply the first equation by 8, and the second by (-5), then add the resulting equations.


When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?

The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.


What is the degree for a number without a variable?

anything without a variable is to the first power. To find the degree, you look at what the power of the number is and that will be the degree. The degree is the number of times your coefficient is a factor. Since the exponent is one, so is the degree. Ex. 2x squared = 2nd degree
