The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.
So the plane's actual speed (with the wind included) is 550-20 = 530 mph.
Good luck!
Answer:
We have: 2x+7y=−1
Let’s express this equation in terms of y:
⇒y=−27x−17
⇒ Gradient =−27
Parallel lines always have the same gradient:
⇒ Gradient of parallel lines =−27
Perpendicular lines have the negative reciprocal of the gradient:
⇒ Gradient of perpendicular lines =72
