Tell whether the ordered pair is a solution of the given inequality. Show your work step-by-step.
1. (1,6);y
Plug the x and y values in and simplify
So #1 would be y<7? And #2 would be y ≥-6+17? And #3 would be y≤7?
I'll do the first one. \[y <x +6\] Since we are told that x = 1 and y = 6 plug those back into the equation. \[6 < 1 + 6\] Now simplify. 6 < 7 Since 6 is less than 7 , #1 is true
Do you understand what I did?
Yes I did
I get it now...
Thanks!
So #2 would be -12≥-6+17 which is invalid so it's not a solution to the equation right?
Where did you get 17 from?
Hold on.. I'm trying to re-solve it...
Never mind it's -12≥-6-5 right?
It's -12≥-11 which is a solution
Well, there negative. -12 is less than -11 - so false
Oh ya... so #3 would be true then right?
\[-3 \le -3\] -3 is less than or equal to -3. So yes, true
Thanks!
