The cost of car service is partly constant and partly varies with the time it takes to do the work it cost $3500 for a 5.5 hour service and 2900 dollars for a 4 hour service. a) find the formula connecting $3 with time T hours.
b) find the cost of a 7.5 hour service.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

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
