Determine the value(s) for which the rational expression −12d−110d+5 is undefined. If there's more than one value, list them separated by a comma, e. g. d=2,3.

The rational expression is not written correctly, so i actually can not know the actual expression.

I will try to answer this in a general way, so you can try to apply it to the actual problem.

Now, suppose that our rational expression is:

The numerator is -12d, this part does not have any problem at any value of d, so we don't have any undefined value here.

The denominator is: -110d + 5

Now, a rational expression is undefined if the denominator is eqeual to zero (we can not divide by zero)

So an undefined value will be when:

-110d + 5 = 0

d = -5/110

This means that we can not have the value d = -5/110, because this makes the denominator equal to zero.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
