Inequalities help only 4 questions. Pleas. (:
Here it is
@robtobey @zepdrix @Luigi0210 anbody who can help? @Psymon please
Mmmmmmm ya your first answer looks good.
Hmm not so much on the second one D: Let's see what's going on.
\[\Large 4p+1\gt-11\]subtracting 1,\[\Large 4p\gt-12\]Dividing 4,\[\Large p\gt-3\]
p is GREATER than -3. Did you accidently flip the inequality sign maybe? :o
Here are my last 2.
I dont think i did them right because this is confusing for me but if you can please explain what i did wrong and the right answer.
\[\Large |2x+1|\le 5\]Dropping the bars gives us,\[\Large -5\le2x+1\le5\]Then solving for x gives us,\[\Large -3\le x\le 2\] Looks like you got the 3rd one correct, lol :) were you just guessing? :3
No, i worked them out the way i was taught to but its confusing for me. I have never been good at math. so i got 3rd correct what about the 4th?
Hmm these absolutes always confuse me also... -_- I think this is how we do it...\[\Large |2x+4|>14\]Dividing each side by 2,\[\Large |x+2|>7\]Dropping the bars let's us write it like ummmm...\[\Large (x+2)>7, \qquad\qquad (x+2)<-7\]
Solving for x gives usssss... Yah I think you got the right answer there also! :O
Haha yeah so freaking confusing but thanks for the help (:
