Answer:
v = -7.5
Step-by-step explanation:
Step 1: Subtract 3v from both sides.
v-17 − 3v = 3v−2 −3v
−2v−17=−2
Step 2: Add 17 to both sides.
−2v−17+17=−2+17
−2v=15
Step 3: Divide both sides by -2.
-2v/2 = 15/2
v = -15/2
v = -7.5

Answer:
C.
Step-by-step explanation:
WE need to convert the given equations into the standard form
(x - a)^2 + (y - b)^2 = r^2 where r = the radius.
x^2 + y^2 + 12x - 20y+ 132 = 0
(x + 6)^2 - 36 + (y - 10)^2 - 100 = -132
(x + 6)^2 + (y - 10)^2 = -132 + 36 + 100 = 4
giving a radius of 2
x^2 + y^2 + 12x - 20y + 55 = 0
will give a right hand side of -55 + 36 + 100 = 81 giving radius 9.
x^2 + y^2 - 12x+ 20y + 127 = 0
- gives right hand side of -127 + 36 + 100 = 9 giving a radius of 3.
-x is 13 units to the right of 0 or -13 units to the left of 0.
Hope this helps :)
