I've done this problem over and over and I keep getting the same answer although my answers are never one of the responses for the multiple choice question. Am I doing it wrong or is the right answer not one of the choices? Here's my work:
Solve the inequality. Write the answer in interval notation.
8 < 3x or -16 + 2x < -23
8 < 3x
÷3 ÷3
8/3 < x
-16 + 2x < -23
+16 +16
2x < -7
÷2 ÷2
x < -7/2
And the interval notation would be (-infinity, -7/2] U (8/3, infinity)
This is a question from an online quiz that I've already completed and submitted. There was a question on the last quiz that didn't have the right choice as an answer which is the only reason I think this might have happened again. I don't want to know the right answer if this is not it, simply just if my work is wrong.
