I think it’s f(x+k) = f(x) + k correct if I’m wrong
Answer:
467.5
Step-by-step explanation:
165 divided by 6 to get 27.5 km per hour
27.5 times 17=467.5
So, just do -20-8=-28 Celsius
Hope this helps!
He first step to solving this question is distributing the three and the four once you have your new equation of 6x+3-8x-20 you can easily add or subtract once you do this you should have -2x-17 which is the answer.
The speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.
<h3>Relative Speed Concept;</h3>
When the plane flies against the wind;
- Relative Speed = 120 = x -y
When the plane flies with the wind;
- Relative Speed = 240 = x +y
Where in;
- The speed of the air plane = x
- The speed of the wind = y
By solving the equations simultaneously; we have;
- x = 180 miles in 2 hours and y = 60 in 2 hours.
Ultimately, the speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.
