Multiply by its reciprocal. What's -3 \(\times\) 5?

OpenStudy (anonymous):

-1<5*3y -6<3y -3<y

OpenStudy (anonymous):

-15

OpenStudy (igreen):

Correct.

OpenStudy (anonymous):

y>-15

OpenStudy (anonymous):

so would it be y<-15 or y>-15??

OpenStudy (igreen):

y > -15

When dividing by a negative number, you ALWAYS switch the sign.
