Solve the inequality and graph its solution


Answer:
Step-by-step 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.
[tex]4+\frac{n}{3} <6\\multiply~by~3\\12+n<18\\n<18-12\\n<6[/tex]
open circle at 6 and extends left .
Answer:
5) b<-10
From -10 to left
6) n<5
From 4 to 1
7) n<6
From 5 to -2
8) r<=4
From 4 to -4
