## Safari321 4 years ago Really need help with this inequality problem............

1. safari321

$5\le 5-2 (4m +7)$

2. anonymous

Do you want to find m ?

3. safari321

yes

4. anonymous

Is M$M \le \frac{ -7 }{ 4 }$ ???

5. anonymous

The steps is below (hope it is correct) $5 \le 5-2(4m+7)$ $5 - 5 \le -2(4m+7)$ $0 \le -2(4m+7)$ $0 \le -8m-14$ $14 \le -8m$ $\frac{ -14 }{ 8 } \ge M$ $\frac{ -14 }{ 8 } \ge M$ $M \le \frac{ -7 }{ 4 }$
