The equation is not typed properly, and it is difficult to understand. But it is clear that you are trying to determine the value of y that makes your equation undefined.
An fraction is undefined if it's denominator is zero, that is if it's of the form a/0.
The value that makes a fraction undefined is the value that makes the denominator vanish. The value that makes its denominator equal to zero.
Example:
1. (x - 3)/(y - 5) is undefined if
y - 5 = 0
Or y = 5
2. (3x² + 4xy + 6)/(x + 2)(y + 6)
If x + 2 = 0, or y + 6 = 0
That is if x = -2, or y = -6
You can use this idea to find the value of y that makes your equation undefined.
Answer:
1 and 2 are not polyhedrons, as a circle has infinite sides
1. cone, 1 vertex
2. sphere, nothing
3. pentagonal prism?
wait but can't every face be a base???
anyway 7 faces, 10 vertices
4. triangular prism
5 faces, 6 vertices

Answer:
Step-by-step explanation:
The two sides opposite the angles marked as equal are themselves equal
4x + 8 = 48 - x Add x to both sides
4x + x + 8 = 48 Combine
5x + 8 = 48 Subtract 8 from both sides.
5x + 8 - 8 = 48 - 8 Combine
5x = 40 Divide by 5
5x/5 = 40/5
x = 8
By definition <span>the rate of change of a function is given by:
</span>

<span />For the interval [0, 2] We have to make use of the table:
<span />

<span />Therefore, substituting values in the given expression we have that the average change of rate is given by:
<span />

<span />Rewriting we have:
<span />
