Question 383493: PLEASE HELP!
I have solved this one but something looks wrong.
Determine whether these numbers are solutions of the inequality :
x-1 (greater then or equal to) 7; -5,1,4,20
I substituted -5,1,4,20 for x in the inequality and solved accordingly.
I found there was NO solution for any of the numbers. Am I wrong and thank you.
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! if x is -5, 1, or 4, then x-1 >= 7 is false.
if x is 20, then x-1 >= 7 is true, because 19 >= 7
-5-1 = -6
1-1 = 0
4-1 = 3
20-1 = 19
