Respuesta :
3x < - 9
x < -9/3
x < -3
The number line will have a clear circle at -3 and will be shaded to the left of the number.
x < -9/3
x < -3
The number line will have a clear circle at -3 and will be shaded to the left of the number.
Answer:
x<-3 i.e. the region in the number line to the left of -3 excluding -3
Step-by-step explanation:
given that inequality as 3x<-9
Since 3 is positive, we can divide this inequality by 3 without disturbing the less than sign
i.e. x<-9/3
Or x<-3
Since strictly less than is there for -3, we must have a hole at -3 (excluding -3)
Since less than sign is there, the region on the number line to the left of -3 with a hole at -3
Hence draw a number line with 0 at centre, mark -3 to left of 0 and circle it.
Shade the region to the left of the smaller circle around -3
