(x + y)2 + ( y + 3)2 = 100

Step-by-step explanation:

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

=

10

h

=

0

k

=

0

The center of the circle is found at  

(

h

,

k

)

.

Center:

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
