Answer:
3x -2y +11 = 0
Step-by-step explanation:
The equation of the line perpendicular to ax+by=c through point (h, k) can be written as ...
b(x -h) -a(y -k) = 0
Simplifying this will put it in general form.
__
You have a=2, b=3, (h, k) = (-1, 4), so your equation is ...
3(x +1) -2(y -4) = 0 . . . . fill in the values
3x -2y +11 = 0 . . . . . . . simplify
Solve for x.
![\frac{9-x}{5} = 3](https://tex.z-dn.net/?f=%20%5Cfrac%7B9-x%7D%7B5%7D%20%3D%203%20%20)
9-x = 15
-x = 6
x = -6
First you multiply 5 on both sides, then -9 and then divide by -1 to eliminate the - sign.
Hope this helps :)
Step-by-step explanation:
(x²-9)/(x+3)
(x²-3²)/(x+3)
(x+3)(x-3)/(x+3)
x-3
x=-3
-3-3=-6
