Question

Which inequality is true when x = 8?

40x > 320
40x < 320
40x < -320
40x ≤ 320

Answer 1

To evaluate the inequalities for \( x = 8 \), we first calculate \( 40x \):

\[
40x = 40 \times 8 = 320
\]

Now, we can check each inequality with this result:

1. **For \( 40x > 320 \):**
\[
320 > 320 \quad (\text{False})
\]

2. **For \( 40x < 320 \):**
\[
320 < 320 \quad (\text{False})
\]

3. **For \( 40x < -320 \):**
\[
320 < -320 \quad (\text{False})
\]

4. **For \( 40x \leq 320 \):**
\[
320 \leq 320 \quad (\text{True})
\]

The only true inequality when \( x = 8 \) is:

\[
\boxed{40x \leq 320}
\]
