Final answer:
The restricted value for the expression (-2)/(b-8) is b = 8.
Step-by-step explanation:
The given expression is (-2)/(b-8). In this expression, the restricted value(s) occur when the denominator, (b-8), becomes equal to zero. To find the restricted value(s), we solve the equation b-8 = 0 for b. Adding 8 to both sides of the equation, we get b = 8. Therefore, the restricted value for (-2)/(b-8) is b = 8.
