Evaluate the expression for j = –8. Simplify your answer.

Question

j
j + 12
=

Answer 1

To evaluate the expression $\frac{j}{j+12}$ for $j=-8$, we will first substitute $-8$ for $j$ in the expression.

1. Substitute $j=-8$:

$$\frac{-8}{-8+12}$$

2. Simplify the denominator:

$$-8+12=4$$

3. Now the expression becomes:

$$\frac{-8}{4}$$

4. Simplify the fraction:

$$\frac{-8}{4}=-2$$

Therefore, the value of the expression for $j=-8$ is $\boxed{{\displaystyle -2}}$.
