-3y>9

a) y<3
b) y>3
c) y<-3
d) y>-3

-3y>9

Divide both sides by - 3.

Remember that when you divide both sides by a negative number the sign changes directions.

Yes, C.

To solve the inequality -3y > 9, we need to isolate y on one side of the inequality sign. Follow these steps:

1. Divide both sides of the inequality by -3. Note that when you divide by a negative number, the inequality flips.
-3y / -3 > 9 / -3
y < -3

So the correct answer is: c) y < -3.
