$$Solve -2x + 1 \le-7$$  and describe the graph of the solution.

anonymous · Answer

What rules of operations with inequalities do you know?

anonymous · Answer

idk

anonymous · Answer

Ok, in general you can treat an inequality just like an equals sign EXCEPT if you multiply or divide both sides by a negative number. If you do so, you must flip the inequality sign. 

So your steps to solve this would be the same as if 
$$-2x+1=-7$$ 
EXCEPT 
if you divide/multiply by a negative number you need to flip the inequality. 
for example 
$$x+10\ge 40 \to x\ge 40-10$$
$$-9x\le 90 \to x\ge 10$$

x  > 4; closed circle on 4, shading to the right

anonymous · Answer

why did you go from 
$$\ge \to >$$ ?

anonymous · Answer

also why a circle, circles involve a y variable, there isn't one. The answer is simpler than a two dimensional graph

anonymous · Answer

i dont konw the answer

anonymous · Answer

Ok so a model for you to use. 

Let's say that  
$$-10x +2 \ge -8$$
then 


$$-10x +2 -2\ge -8-2$$
becomes
$$-10x \ge -10$$
divide both sides by (-10) and remember to flip the inequality
$$x \le 1$$
graphing this is the same this as showing graphically that x is less than or equal to 1. 
|dw:1351975566818:dw|
would be the graph. 

Try using this model as a tool to solve your problem.
