Answer:
step 1. Angle bisector theorem.
step 2. 14/6 = 21/ (3x - 12)
step 3. 14(3x - 12) =21(6)
step 4. 6x - 24 = 18
step 5. 6x = 42
step 6. x = 7.
The general form would be:

where 'a' is responsible for the magnitude of the function, 'b' is responsible for horizontal shift.and 'c' is responsible for vertical shift of the function.
Your answer would be:

Looks like choice A
Answer:
Step-by-step explanation:
Given that your friend tossed a fair coin when you weren’t around.
Let A be the event that she said the outcome is head
B1 = Event she lied and B2 = Event she did not lie

P(AB1) = 
P(AB2) = 
Required probability = P(B1/A)=
64x + 38y + 10 is your answer......
