how do you solve this compound inequality
5>4x+4 or 9<or equal to 3x+4

5>4x+4
1>4x
(1/4) > x
1/4 <x change direction of arrow when multiplying both sides by negative value.
so
x> 1/4 is in (everything right of 1/4)
now
9</=3x+4
5 </= 3x
5/3 >/= x
so
x </= 5/3 is in (5/3 and everything left of that)
graph that
The only part of the x axis that is not in your domain is between right of 5/3 and 1/4 including 1/4
