If you are asking for the formula thing, it is
y=3x+2
2y+4x=12
Move 4x to the other side as a negative number
2y=-4x+12
Divide all terms by 2
y=-2x+6
Now, in order for two lines to be perpendicular, their gradients have to multiply obeyed to get -1 (let a be the gradient of the given line and let b be the gradient of the line we're trying to find)
So, we do -2*b=-1
so, b is equal to 1/2
Now, we are given a coordinate so we substitute it in y-y1=m(x-x1)
y-1=1/2(x-8)
Expand brackets
y-1= 1/2x-4
Take -1 to the other side as a positive number
y=1/2x-3
So, the equation of the line is y=1/2x-3

Answer:
606.6 and 233.3 respectively
Step-by-step explanation:
Let the speed of plane in still air be x and the speed of wind be y.
ATQ, (x+y)*9=7560 and (x-y)*9=3360. Solving it, we get x=606.6 and y=233.3
Answer:
Hi again, I'm here to answer!
The correct answers:
10. x = -7 2/3
11. x = 2
12. x = 3
Step-by-step explanation:
(x + 3)/2 = (x - 4)/5
(5x + 15)/10 = (2x - 8)/10
3x/10 = -23/10
x = -23/3
x = -7 2/3
(2x - 1)/3 = x/2
(4x - 2)/6 = 3x/6
x/6 = 2/6
x = 2
(3x + 1)/5 = 2x/3
(9x + 3)/15 = 10x/15
-x/15 = -3/15
x = 3
Hope this helped!
