Really need help with this inequality problem............
Do you want to find m ?
Is M\[M \le \frac{ -7 }{ 4 }\] ???
The steps is below (hope it is correct) \[5 \le 5-2(4m+7)\] \[5 - 5 \le -2(4m+7)\] \[0 \le -2(4m+7)\] \[0 \le -8m-14\] \[14 \le -8m\] \[\frac{ -14 }{ 8 } \ge M\] \[\frac{ -14 }{ 8 } \ge M\] \[M \le \frac{ -7 }{ 4 }\]
