I think this question has a typo because none of the multiple choice answers fit.
The question is which of the following values is in the solution set of inequality 8-7x<-6?
A) -3 B)-2 C)2 D)-6
A if you plug in -3 you get
B) 8+14<-6 no
c) 8-14<-6 so -6<-6 no
D) 8+42<-6 no
Did I do something wrong or are there no correct answers?
-7x < -6 -8
-7x < -14
x = 2
x can be any number smaller than 2.
so is there one of the multiple choice questions that are correct, since three numbers in the multiple choice that are less than 2. As you see above
Ahh -- but the other solutions are negative number. The answer for c, 2, is the only solution that is positive.
I went on the website you showed me. It said when you mult. or divide a neg, like -7x you change the sign, so shouldn't it be that x>2.
I am really confused
when you check your answer and put 2 in to do a check it comes out
this is not true unless it was greater than or equal to, that is why I believe there is no correct answer to the question. Isn't that right?
