2 Multiply both sides by −1
n<0
Answer:
N<0
So yes, this is possible.
Answer:
Irrational
Step-by-step explanation:
it can not be written as a simple fraction
Answer:
x = -1
Step-by-step explanation:
1.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
2.1 Solve : -2 = 0
x = -1
Speed = dis / time
let plane speed in still air is X and air speed Y
so, X-Y = 2280/4 = 570 km/h
and X+Y = 6650/7 = 950 km/h
so, X = (570 + 950) / 2 = 760 km/h
and Y = 950- 760 = 190 km/h
