Your answer In the past year, Anna's mom has spend $7440 on her rent. What is the unit cost
(dollar per month)?

$620

Step-by-step explanation:

If the payment is equally distributed for each month, it will be $620/month. The way to find this answer is to divide the money spent by the months they were spent. Since there are 12 month in a year, you dive $7440/12, which is $620!

8

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
