Mathematics

KiRa [710]3 years ago
6 0

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

3x < -9

solve for x

Divide by 3 both sides

3x/3 < -9/3

x < -3

The solution is the interval------>(-infinite, -3) -

All real numbers less than -3

In a number line the solution is the shaded area to the left of the dashed line (open circle)

see the attached figure
