Answers:

Domain = [-5, -2] \cup [1,5)

Range = (-4,4]

=============================================

Explanation:

The domain is the set of allowed x value inputs. We note that the left-most point is when x = -5, and this point has a closed or filled in endpoint, so we're including this x value in the domain.

The left piece has its other endpoint at x = -2, so the interval -5 \le x \le -2 is part of the domain. We write that as [-5,-2]is part of the domain's answer. The other part is [1, 5). We include x = 1 but exclude x = 5 as there's a hole here.

Use the union symbol to glue the two intervals together and we end up with [-5, -2] \cup [1,5) as the full domain.

----------------------------

The range is the set of possible y values. The lowest point is when y = -4, but we exclude this endpoint since there's an open hole here. The highest point is when y = 4. The range is -4 < y \le 4 which we write as (-4, 4]

Since there are no gaps in the range, we don't use any union symbols here. Any y value between -4 and 4 is possible, other than y = -4 itself.

Find the x intercept and y intercept for 6x-2y=18 . provide an explanation and show steps
allochka39001 [22]

Answer:

The slope intercept form would be y = 3x - 9

Step-by-step explanation:

To find this slone in slope intercept form, all we need to do is solve for y.

6x - 2y = 18 ---> Subtract 6x from both sides

-2y = -6x + 18 ----> Divide both sides by -2

y = 3x - 9

What is the value of x? leave your answer in simplest radical form.
Masteriza [31]

Answer:

2 sqrt(5) =x

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

2^2 +4^2 = x^2

4+16 = x^2

20 = x^2

Take the square root of each side

sqrt(20) = sqrt(x^2)

sqrt(4*5) = x

sqrt(4) sqrt(5) =x

2 sqrt(5) =x

The equation X squared plus Y squared minus 2X plus 7Y +1 equals zero can be written as which of the following equations
ad-work [718]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

  • x squared plus y squared: x ^ 2 + y ^ 2
  • minus 2x plus 7y plus 1: -2x + 7y + 1
  • equals zero: = 0

We construct the equation:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

Answer:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

How can you solve an equation with a variable on ni tu sides?​
Vesnalui [34]

Answer:

  Subtract from both sides of the equation the term you don't want

Step-by-step explanation:

In solving equations, you generally want to "undo" operations that are done to the variable. Addition is "undone" by adding the opposite (that is, subtracting the amount that was added). Multiplication is "undone" by division.

If you have variables on both sides of the equation, pick one of the variable terms and subtract it from both sides of the equation.

<u>Example</u>

  2x = x +1

If we choose to subtract x, then we will have a variable term on the left and a  constant term on the right:

  2x -x = x -x +1 . . . . . . . x is subtracted from both sides

  x = 1 . . . . . . simplify

__

Note that we purposely set up this example so that removing the variable term from the right side caused the variable term and constant term to be on opposite sides of the equal sign. It may not always be that way. As long as you remember that an unwanted term can be removed by subtracting it (from both sides of the equation), you can deal with constant terms and variable terms no matter where they appear.

_____

<em>Additional Comment</em>

It usually works well to choose the variable term with the smallest (or most negative) coefficient. That way, when you subtract it, you will be left with a variable term that has a positive coefficient.
