31 = -4v - 5
31 (+5) = -4v -5 (+5)
36 = -4v
36/(-4) = -4v/(-4)
36/ -4 = v
v = -9 is your answer
hope this helps

Answer:
It's exponential growth.
Step-by-step explanation:
b/c any value of b that's greater than 1 is an exponential growth function, and anything that's 0<b<1 or if b<0, the function would be an exponential decay.
Answer:
42 ft
Step-by-step explanation:
14 times 14=196
R of circle =7
7 squared=49
49 times pi= 153.938040026
196-153.938040026= 42.0619599741
Rounded to 1 decimal=42.1
Rounded to whole number = 42
Answer: SAS
Step-by-step explanation:
Here ABC is a triangle, In which angle BAC is bisected by line AR where, 
.
Thus in triangles ABR and ACR,
AB= AC ( given)
Therefore 
( by the property of angle bisector)
And, 
(reflexive)
Thus by SAS postulate,
△ABR ≅ △ACR.
Therefore, Option D is correct.
