Answer 1

Explanation:

6.

-4(3+n)>-12

-12-4n>-12

-4n>0

n<0

open circle at 0 and left of 0 on the number line.

8.

-3(r-4)≥0

divide by -3

r-4≤0

r≤4

solid line starting from 4 and extends left .

5.

-b-2>8

-b>10

b<-10

open circle at -10

and extends left.

7.

`4+(n)/(3) <6\\multiply~by~3\\12+n<18\\n<18-12\\n<6`

open circle at 6 and extends left .
