Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.

Answer:
<u>The</u><u>r</u><u>e </u><u>are </u><u>5</u><u>0</u><u> </u><u>oranges </u><u>in </u><u>the </u><u>box.</u>
Step-by-step explanation:
Weight of box = 4 kg = 4000 g
Weight of 1 orange = 80 g
No. of oranges in the box = ?
No. of oranges in the box = Weight of the box / Weight of 1 orange
No. of oranges in the box = 4000 / 80 = <u>50 oranges.</u>
