A feasible region is defined by the following constraints: , , , and . Find the coordinates of the vertex that is the intersection of the two non-axis boundary lines.
Solve the inequality for :
A bakery makes loaves of bread and cakes. Each loaf needs 3 cups of flour and each cake needs 2 cups. The bakery has a maximum of 60 cups of flour available. Which inequality represents this constraint?
![ A coordinate plane showing a dashed line that intersects the y-axis at 3 and the x-axis at 4. The region below and to the left of the line, including the origin (0,0), is shaded. ] Identify the inequality representing the shaded region.
