Answer:
Option (c) is correct.
The values that are excluded for the given expression [tex]\frac{x-7}{x+9}[/tex] is -9 .
Step-by-step explanation:
Given: Expression [tex]\frac{x-7}{x+9}[/tex]
We have to find the values that are excluded for the given expression [tex]\frac{x-7}{x+9}[/tex]
For rational numbers , we exclude those values for which the denominator of the rational expression is 0.
Consider the given expression [tex]\frac{x-7}{x+9}[/tex]
Denominator of the given expression is x + 9
Put x+ 9 = 0
We have x = - 9
Thus, The values that are excluded for the given expression [tex]\frac{x-7}{x+9}[/tex] is -9 .
