Answer:

Option B.

Step-by-step explanation:

A function is represented by the table given in the question.

We should always remember that for a function plotted on a graph or table representing x and y-coordinates, x value will always represent Domain and y- values define the range of the function.

Therefore x values {2, 4, 6, 8} represent the domain of the function and y values represent the range.

Option B. {2, 4, 6, 8} is the answer.

The length of a rectangle is three times its width. One way to write an expression to find the perimeter would be

navik [9.2K]

It could be written as 8w the simplified version of the example.

Or you could write it as 2(3w + w) which is 2 time the length and width.

the equation of a circle in general form is x squared + y squared + 20x + 12 y + 15 equals 0what is the equation of the circle i

Marrrta [24]

Answer: $(x+10)^2+(y+6)^2=121$

Step-by-step explanation:

The equation of a circle in the general form is:

$ax^{2}+by^2+cx+dy+e=0$

The equaton of a circle in standard form is:

$(x-h)^2+(y-k)^2=r^2$

Where the center is at (h, k) and r is the radius

To write the equation of a circle from general form to standard form, you must complete the squaare, as you can see below:

1- Given the equation in general form:

$x^{2}+y^2+20x+12y+15=0$

2- Complete the square:

-Group the like terms and move the constant to the other side.

- Complete the square on the left side of the equation.

- Add the same value to the other side.

Then you obtain:

$(x^{2}+20x)+(y^2+12y)=-15\\(x^2+20x+(\frac{20}{2})^2)+(y^2+12y+(\frac{12}{2})^2)=-15+(\frac{20}{2})^2+(\frac{12}{2})^2\\\\(x+10)^2+(y+6)^2=-15+100+36\\(x+10)^2+(y+6)^2=121$
