Graph each circle given below. write the center and the radius of each circle x2+y2=9

Center: (0,0)

Radius: 3

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

Where (h,k) is the  point of the center of the circle and r is the radius of the circle.

If the center is at (0,0) and the radius is 3, you obtain the equation given in the problem:

Therefore, the center is (0,0) and radius is 3.

You can graph the circle with its center at the origin and a radius of 3 as you can see in the figure attached.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
