$f (10) = \frac{89 t}{99 - t - 89}$

Step 1

Replace the variable $t$ with $10$ in the expression.

$f (10) = \frac{89 (10)}{99 - (10) - 89}$

Step 2

Multiply $- 1$ by $10$ .

$f (10) = \frac{89 (10)}{99 - 10 - 89}$

Step 3

Subtract $10$ from $99$ .

$f (10) = \frac{89 (10)}{89 - 89}$

Step 4

Subtract $89$ from $89$ .

$f (10) = \frac{89 (10)}{0}$

Step 5

The expression contains a division by $0$ . The expression is undefined.
