X=y-bm is the answer you are looking for
Answer:

Step-by-step explanation:
Differentiating, you get ...
... x·dy +y·dx +dx +dy = 2x·dx +2y·dy
Collecting terms gives ...
... dy(x +1 -2y) = dx(2x -y -1)
... dy/dx = -(2x -y -1)/(2y -x -1)
Answer:
He would have to talk 200 minutes.
Step-by-step explanation:
Since 30 divided by .15= 200. And there is a .15 cent cost per minute meaning Javier would have to talk for 200 minutes for the prices to be equal.

Answer:
y = (-2/3)x + 1
Step-by-step explanation:
3y = -2x + 6
y = (-2/3)x + 2
y + 3 = (-2/3)(x - 6)
y + 3 = (-2/3)x + 4
y = (-2/3)x + 1
