Question 1182814: Given 3x+bx-8> -14, determine the largest integer value of b when x=-2
Please tell the largest integer value and please helps me understand what it means.
I plugged in the -2 first
3(-2)+b(-2)-8> -14
Then I simplified
-6-2b-8> -14
Then I added by 8 on both sides
-6-2b>-6
Then added 6
-2b>0
Then divided by -2 and got
b>0
What would the largest integer value be?

Given 3x+bx-8> -14, determine the largest integer value of b when x=-2 
Please tell the largest integer value and please helps me understand what it means.  
I plugged in the -2 first 
3(-2)+b(-2)-8> -14 
Then I simplified 
-6-2b-8 > -14 
Then I added by 8 on both sides 
-6-2b > -6 
Then added 6 
-2b > 0 
Then divided by -2 and got 
b > 0      <-- THAT'S WRONG!  IT SHOULD BE b < 0
            WHEN YOU DIVIDE AN INEQUALITY THROUGH BY A NEGATIVE
            NUMBER, YOU MUST REVERSE THE INEQUALITY SYMBOL.  
What would the largest integer value be?

           The largest integer that is less than 0 is -1.
