Does the value y=-4 satisfy the inequality 2y+5>7? Thanks so much.

jimthompson5910 (jim_thompson5910):

Start with 2y+5>7 and replace 'y' with -4 to get 2y+5>7 2(-4)+5>7 Now simplify the left side. Tell me what you get.

OpenStudy (anonymous):

\[-8+5>7\] then i got -3>7

jimthompson5910 (jim_thompson5910):

is -3 larger than 7?

OpenStudy (anonymous):

No its less than 7

jimthompson5910 (jim_thompson5910):

So -3>7 is false

jimthompson5910 (jim_thompson5910):

which means 2(-4)+5>7 is false

jimthompson5910 (jim_thompson5910):

which means 2y+5>7 is false when y = -4

OpenStudy (anonymous):

Thanks a millin for your help!

jimthompson5910 (jim_thompson5910):

So y = -4 does NOT satisfy 2y+5>7
