7.7 inches, = 4.2 inches and =7.3 inches

Graph (B)

Step-by-step explanation:

Given inequality is,

x + 2y ≤ 47

This inequality has a sign of less than equal to ( ≤ ).

Properties of this inequality when graphed will be,

1). Sign of equal to in the given inequality shows that the graph of the line will be a solid line.

2). Sign of less than represents the shaded region below the line.

Therefore, Graph (B) will be the answer.
