Answer:
x = - 15
Step-by-step explanation:
Given
+ 3 = x - 2
Multiply through by 3 to clear the fraction
4x + 9 = 3x - 6 ( subtract 3x from both sides )
x + 9 = - 6 ( subtract 9 from both sides )
x = - 15
Answer:
the four point cannot be on the same line , but they have to be on the plane.
A D C E
collinear means on the same line
so ABC
non-coplanar means the point do not lie on the same plane so you can include point F
F A D B
1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)
x+3 =1/(y+4)
x= 1/(y+4) - 3
2) change x on y , and y on x
x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.
