Answer:x<-3 example, in the region on the number line to the left of -3 excluding -3step-by-step explanation:since the inequality 3x<-9Since 3 is positive, we can divide this inequality by 3 without disturbing the less signi.e. x<-9/3 Or x<-3Since strictly less that is there to -3, we must have a hole in -3 (excluding -3)From the less-than sign is there, to the region on the number line to the left of -3 with a hole in 3Hence draw a number line with 0 in the center, the mark of -3 to the left of 0 and the circle.The shadow of the region to the left of the smaller circle of around -3
