Answer:
D
Step-by-step explanation:
Given V varies inversely as T, then the equation relating them is
V = 
← k is the constant of variation
To find k use the condition, V = 12 when T = 6
k = VT = 12 × 6 = 72
V = 
← equation of variation
Start by writing what is said:
2x + 4 = -6
From there just solve for x:
Subtract 4 from both sides
2x + 4 - 4 = -6 - 4
2x = -10
Divide by 2 to get x by itself
2x/2 = -10/2
x = -5
