Hi there,

Question 1: since the region is below the line y=4 and the boundary region is a dashed line, the inequality is y<4.
Question 2: since the region is below the line y=0, the inequality is y<=0.
Question 3: the second choice "150 pounds of hamburgers and 60 pounds of hotdogs" is right.
Question 4: since the region on the left side of x=5, the inequality ...
