At Cinemania Movie Theater, movie tickets for a family of 2 adults and 3 children cost $28. Tickets for a family
of 1 adult and 2 children cost $22. How much does an
adult ticket and a child ticket cost?
Oa= 2 + 1
c= 3 + 2
O2a + 3c = 22
a + 2c = 28
O2 + a +3+ c = 28
1 + a + 2 + c = 22
O2a + 3c = 28
a + 2c = 22

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
