What else can I help you with?
Which properties justify the steps taken to solve the system x plus y 2x plus and minus Drag the answers into the boxes to match each step.?
To solve the system of equations involving ( x + y ) and ( 2x + y ), we can use properties such as the substitution property, where one variable is expressed in terms of the other, and the addition property of equality, which allows us to add or subtract equations. Additionally, the distributive property may be used when simplifying expressions. Each step taken in solving the equations should maintain the equality of the system through these properties.
How do you solve 2x plus 20?
It is simply 2x+20 which is an algebraic expression that has no equality sign.
What does the division property of equality allow you to do?
you can just use multilecation to do division The division POE (property of equality) Allows you to divide each side of an equation by the same number. If I were solving for x in this equation, I would use the division POE -2x = 4 /-2 /-2 x = -2
How can you use the addition and subtraction properties of equality to produce equivalent inequalities?
This is the kind of thing to which I think you are referring. You have an equation such as 4x + 5 = 2x + 3. You can subtract 2x from both sides to obtain, 2x + 5 = 3, then add -5 to both sides to obtain 2x = -2, then divide both sides by 2 to obtain x = -1. You can do very much the same thing with an inequality such as 4x + 5 lt 2x + 3. The same steps yield x lt -1.
Whai is the solution to Ln 2x plus 9 equals ln 5x?
That all depends.Is it:ln (2x+9) = ln (5x)If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.

How do you factor 4x2 plus 2x-6 equals 0?
If 4*2+2x-6=0 is what you meant, then I am going to say 2(2*1+1x-3) is your answer Edit: if solving for x then -1 is your answer, sorry I'm used to solving for multiple possibilities for x so "factor" threw me off.

What is 3x-2x 34?
It is 3 terms of an algebraic expression and it is not an equation because it has no equality sign.
What can you say about the end behavior of the function f(x)- In (2x) plus 4?
You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.

Solving 2x plus y equals 10 and y equals x-5 subtitution?
2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0
What is the answer to 6x-2x-3 equals 31?
6x - 2x - 3 = 31 grouping the expressions with x: 6x - 2x = 31 + 3 simplifying: 4x = 34 solving for x x = 34/4 = 8.5
What is the following equation for x 2x 32x 6?
Without an equality sign it can't be considered to be an equation.
Which point lies on the line whose equation is 2x-3y9?
Without an equality sign it can not be considered to be an equation
What is x if 2x 3 x 9 is the equation?
Without an equality sign it can't be considered to be an equation.
