How do you solve and graph #abs(2z-9)<=1#?
Find the two values of
The inequality will be true for those values and all values in between.
Separate into two equations:
Multiply both sides of the second equation by -1:
Add 9 to both sides of both equations:
Divide both sides of both equations by 2:
The inequality will be true between these values:
So Values of z
in Graph there are two lines z=4 and z=5
