Answer 1

the easy way to do this is to find the intercepts

start with

p + a >= 30

let a = 0 and solve for p

next let p = 0 and solve for a

now you have the intercepts ... draw the line

pick a test point not on the line... say the Origin (0,0)

substitute the values and see if the inequality is true...

if its true, that's the side of the line to shade...

if its false... shade the other side of the line...

repeat the process with the other line...

find the intercepts

get a test point and test the inequality...

shade the region...
