Question

Determine whether the given numbers are solutions of the inequality.
6, -12,-17,-2
y-10>2y-2
Is -12 a solution? Answer please

Answer 1

I think you're supposed to substitute those numbers in for y then then see if the inequality is true....

Answer 2

6-10>2(6)-2
-4>12-2
-4>10 is FALSE

-12-10>2(-12)-2
-22>-26 is TRUE

so -12 is a solution

Answer 3

you should know how to do it now. you could post your answers for the last two if you want us to check your answers

Answer 4

oops

Answer 5

Okay, I deleted the other one...so yeah, she can check the last two

Answer 6

this simplifies to y < -8
so -12 and -17 are solutions

Answer 7

I was wondering if you could simplify it like that or not

Answer 8

Okay so.-2-10>2(-2)-2
-12>-6 right?

Answer 9

yep i think you can
take y to left to give y on right
and on left -10 + 2 = -8

Answer 10

try plugging the 4 values into the original equality - -12 and -17 check ok
i haven't tried the other 2 yet lol!

Answer 11

-2 is not a solution correct?

Answer 12

correct - nor is 6 - i just tried them
