Answer:

z < 70

Plot a point at 70 and make a ray pointing towards the left.

Step-by-step explanation:

-0.3z > -21

Divide by -0.3 on both sides

z < 70

(Double check, say if z was -30, plug into the inequality)

Make a number line, start from 0 and go up by 5.

You would end with 100.

Plot a point at 70 and make a ray pointing towards the left.

Hope this helps :)

Have a good day!
