Find the word or phrases that best complete the sentence intersecting planes ___ intersect in exactly one point
mars1129 [50]

Answer:

never

Step-by-step explanation:

Intersecting planes are planes that intersect along a given line.

To explain this better, consider the following definitions:

i. A point: This is denoted by a dot and it is a location marked on a space or a plane.

ii. A line: This is the distance between two points. It is one-dimensional.

iii. A plane: This is a two-dimensional, flat surface with no thickness formed by points and extends infinitely.

Therefore, since intersecting planes intersect along a line, it is not possible that they intersect in exactly one point given that a line is the distance between points.

If f(x) = 2x^2-x-6 and g(x) = x^2-4 , what is the domain of f(x) divided by g(x)
Gelneren [198K]
(2x^2-x-6)/x^2-4

Factor top and bottom and you get

(2x+3)(x-2)/(x+2)(x-2)

The (x-2) cancel out each other leaving,

(2x+3)/x+2

The domain is all real numbers EXCEPT for -2. The domain can never be -2 as it would to the bottom having a zero, and that can't happen
