Answer:
43.16 mg
Step-by-step explanation:
After each hour, the amount remaining is 100% - 12% = 0.88 times the amount present at the beginning of the hour. Then after 8 hours, the amount remaining will be the initial amount multiplied by 0.88 eight times, or ...

y = 7
Step-by-step explanation:
Given:
x1 = -2
y1 = 7
slope (m) = 0
y - y1 = m ( x - x1 )
y - 7 = 0 ( x - (-2) )
y - 7 = 0 ( x + 2 )
y - 7 = 0
y = 7
