For what values (cases) of the variables the expression does not exist: a/2x−4
1 answer:
Answer:
x=2
Step-by-step explanation:
Given the expression:
The expression is undefined or "does not exist" when the value of the denominator equals zero.
Therefore, set the denominator of the function equals to zero to find the values at which it does not exist.
2x-4=0
2x=4
x=2
Therefore, at x=2, the function is undefined.

Given:
M is the midpoint of AB.
M(2,0) and A(-3, 3).
To find:
The coordinates of point B.
Solution:
Midpoint formula:
Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get
On comparing both sides, we get
And,
Therefore, the coordinates of point B are (7,-3).
