Answer: -43/20
Step-by-step explanation: you just need a college calculator to solve ,you need to just plug the numbers and it will do it for you.
Just did a specific one of these; let's do the general case.
The point nearest the origin is (a,b).
The line from the origin through the point is

The line we seek is perpendicular to this one. We swap the coefficients on x and y, negating one, to get the perpendicular family of lines. We set the constant by plugging in the point (a,b):


That's standard form; let's plug in the numbers:


7 + 7 + 5 + 5 (two sides are 7 and two sides are 5) = 24
Answer:

Step-by-step explanation:
x² + 6x + 1 = 0
a = 1 , b = 6 , c = 1

1.15(300).
Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.
1.15(300)=345 miles per hour
After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).
