Could someone show me how to solver this problem Please!!!
Find allnumber for which the rational expression is undefined?
6/y-9
The expression is undefined when the denominator is equal to zero.
Thanks GP
To find the values for which the rational expression 6/(y-9) is undefined, we need to identify the values of "y" that make the denominator equal to zero. Remember, division by zero is undefined in mathematics.
In this case, the denominator is "y-9". So, we set y-9 equal to zero and solve for "y".
y - 9 = 0
To isolate "y", we can add 9 to both sides of the equation:
y = 9
Therefore, the rational expression 6/(y-9) is undefined when y = 9, since dividing by zero is not possible.
So, the value for which the rational expression is undefined is y = 9.
