Answer:
B. -1
Step-by-step explanation:
I calculated it logically
The equation and steps are...
First, find the slope of the original equation. In this case, the slope is -8. You know that perpendicular lines have slopes that are negative reciprocals, so the negative reciprocal of -8 is 1/8.
Now, use this new slope and the given point to find the y-intercept:
y = mx + b
4 = (?)(2) + b
4 = ? + b
15/4 = b
Use the new slope and y-intercept to write the new linear equation:
Answer:
y = 1/8x + 15/4
Sorry if i'm wrong
seemed easy
Answer:
The speed of the plane with no wind is 378 miles per hour.
Step-by-step explanation:
Since at maximum speed, an airplane travels 1680 miles against the wind in 5 hours, and flying with the wind. the plane can travel the same distance in 4 hours, to determine what is the speed of the plane with no wind, the following calculation must be performed:
Against the wind = 1680/5 = 336
With the wind = 1680/4 = 420
420 - ((420 - 336) / 2) = X
420 - 42 = X
378 = X
Therefore, the speed of the plane with no wind is 378 miles per hour.
You didn't put your label and also the answer would be 299 36+36+68+68+91=299
Pythagoras: A^2 + B^2 = C^2 where c is the side opposite the hypotenuse (opposite the right angle) and B and C are the other sides. Trigonometry: SOH CAH TOA where you can use their formula where sin = opposite/ hypotenuse Cos= adjacent/ hypotenuse Tan= opposite/ adjacent
