Answer:
D. 
Step-by-step explanation:
First, move the variable (+ 2y) to the left-hand side and change its sign.
Then, move the constant (+ 7) to the right-hand side and change its sign.
Then, collect the like terms (y - 2y)
Finally, add the numbers (3 + 7). That will get you your final answer.

Answer:
b = 18
Step-by-step explanation:
From an external point, the products of distances to the near circle intercept and the far circle intercept are the same. For a tangent, such as AC, point A is both the near and far intercept point, so that product is the square of the length of AC.
(AC)² = (CG)(CV)
b² = 12·27 = 324 . . . . substitute known values
b = √324 . . . . . . . . . . take the square root
b = 18

Answer:
y=2x-3
Step-by-step explanation:
1. find the slope
6x-3y=21
-3y=-6x+21 divide both sides by -3
y=2x-7
slope is 2
2.y-5=2(x-4)
y-5=2x-8
y=2x-8+5
y=2x-3
PARALLEL lines have the same slope
