Solve the inequality. Graph the solution. 3p+2≥−10 The solution is

jhonyy9:

like a first step subtract from both sides 2 so what will get ?

jhonyy9:

@supie any idea ?

supie:

So when i subtract 2 from both sides i got $$3p≥−12$$ because $$3p+2−2≥−10−2$$ -10-2=12 so $$3p≥−12$$ then divide both sides by 3 ???

jhonyy9:

continue pls.

jhonyy9:

@killer ok ?

supie:

Ok so $$\LARGE\frac{3p}{3}≥\frac{-12}{3}$$ $$\cancel{\frac{3p}{p}}≥\frac{-12}{3}$$ (3p/p cancels) so all that is lef tis $$\frac{-12}{3}$$ so that needs to be simplified $$\frac{-12}{3}=?$$ $$p≥?$$

supie:

left is * ._.

jhonyy9:

3p/3 not 3p/p

supie:

Oh that's what I meant.

jhonyy9:

@supie

supie:

Yes i know. I meant $$\frac{3p}{3}$$ but I accidently did $$\frac{3p}{p}$$

jhonyy9:

questions ?

jhonyy9:

@supie how you graph the solution ?
