Find the standard equation for the circle with center on the negative y -axis and passing through the origin with radius of 3.

A. x^2 + y 2 = 9
B. (x + 3)^2 + y^2 = 9
C. x^2 + (y + 3)^2 = 9

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
