PLEASE HELP
Circle A has circumference 2 2/3 m. Circle B has a diameter that is 1 1/2 times as long as Circle A’s diameter. What is the circumference of Circle B?

8 meters.

Step-by-step explanation:

Formula:    Circumference  C = 2*π*r

Circle A circumference:    a = 2 and 2/3 m = 2*π*r

circle B has diameter = 1 and 1/2 *  2r =  (3/2)* 2r = 3r

so

Circumference of circle B  = 2*π*(3r)

here r =   (8/3)/(2*π)=  4/(3*π)

B  = 2*π*(3*  (4/(3*π)) )  = 2*π* (4/π)  = 8 meters.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
