Question

How do I solve and graph this inequality? 12x + 4 ≥ 16 or 3x – 5 ≤ –14

Answer 1

Solve it like an equation but remember that the inequality changes if you divide or multiply by a negative number.

Answer 2

I am new to this, could you help me do this problem? If I solve it like an equation... where do I start?

Answer 3

Ok, so the first inequality is
\[12x \ge 16-4\]
\[12x \ge \]
\[x \ge \frac{ 12 }{ 12 }\]
\[x \ge 1\]

Answer 4

\[12x \ge 12\]

Answer 5

Okay, got it... so then is the second one x \[x \le 6\] ?

Answer 6

\[3x \le -14+5\]
\[3x \le -9\]
\[x \le \frac{ -9 }{ 3 }\]
\[x \le -3\]

Answer 7

Oh, okay, I think I see what I did wrong here... so then to graph this...?

Answer 8

Just ask questions if you have any. Graphing it is actually really simple, do you know what a numberline is?
