Answer:
x= 6, -4
Step-by-step explanation:
x^2 - 2x - 24 = 0
(x-6) (x+4) = 0
x = 6, x= -4
Answer :The first one
Step-by-step explanation:
The three points give you three equations, which you can solve by your favorite method.
.. 0m +0n +b = 6
.. 1m +0n +b = -3
.. 0m +2n +b = 5
(m, n, b) = (-9, -1/2, 6)
so the equation of the plane can be written as
.. z = -9x -1/2y +6
_____
In standard form, this would be
.. 18x +y +2z = 12
Answer: exact form: 7/5
Decimal form: 1.4
Mixed form: 1 2/5
Step-by-step explanation:
X=-9
-x=9 so x=-9 since you inverse the sign
