Solve the inequality \(2x - 5 \le -x +12 \) Give your answer as an interval.

 

 

Solve the inequality \(-4(x + 4) > x + 7\) Give your answer as an interval.

It's just two, not a big deal in my opinion. Any more than that would be an overload.

1.

 \(2x-5\le-x+12\\ =3x\le17\\ =x\ge\frac{17}{3}\\ \boxed{x\in(-\infty, \frac{17}{3}]} \)

 

2. \(-4(x+4)>x+7\\ =-4x-16>x+7\\ =5x<-23\\ x<-\frac{23}{5}\\ \boxed{x\in(-\infty, -\frac{23}{5})}\)

first one is right, but the second one is wrong. Try again!

I reworked it but nothing was wrong...?

Oh you're right! I put a bracket on the back instead of a close paranthesis. Sorry!
