Asked by Es

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
29<-6 no
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?
Thank you

8-7x<-6

-7x < -6 -8

-7x < -14

x = 2

Answered by Ms. Sue
x can be any number smaller than 2.

Answered by Es
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
Thank you
Answered by Ms. Sue
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
Answered by Es
when you check your answer and put 2 in to do a check it comes out
8-7x<-6
8-7(2)
8-14<-6
-6<-6
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?
