y2 -y1 over x2 - x1
Step-by-step explanation: plz mark brainliest
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:

With the wind against the speed is:

Rewriting both equations, we have the following system of equations:

Then, solving the system of equations (graphically for example), we have the solution is:

Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
I believe the answer would be 36.
Hope this helped you. ;}
Answer:
Step-by-step explanation:
(0,2\5)
Slope=4\5
X(4\5)=y-2\5
Y=(4\5)x +2\5
V= W × H × L
81000 = 30 × H × 45
81000 = 1350× H
81000/1350 = 1350/1350× H
H = 60 cm
