1. n≥-9
2. n>6
3. n≤-63
4.n≥4
5.n<7
6.n>-2
7.n<-3
8.n<12
Answer:
x=7 ................................
Let t represent the time the stone fell in the air.
distance = speed * time
t*16 + (12-t)*3 = 127 . . . . . total length of travel
13t = 91
t = 7 . . . . . time in air
The stone fell 7 seconds in the air, then 5 seconds in the water.
