for which rational expression is -5 an excluded value of x?
a) x-5/6
b) x+5/6
c) 6/x-5
d) 6/x+5

D

Step-by-step explanation:

An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.

Consider expression D

This will be undefined when

x + 5 = 0 ⇒ x = - 5 ← excluded value → D

D) 6/x+5

Hope this helps :)

Have a great day !

Step-by-step explanation:

In this example, we will use D

x + 5 = 0 ⇒ x = - 5 ( Excluded value )
