For the equation y - x < 0,
y < x
The shaded portion will be under the dashed line joining points (-2, -2) and (3, 3).

for the equation x - 1 > 0,
x > 1
The shaded portion will be to the right of the dashed line joining points (1, 5) and (1, -3).

The portion affected by the two shadings will be the portion common to the right of the dashed line joining points (1, 5) and (1, -3) and under the dashed line joining points (-2, -2) and (3, 3).
Therefore the correct answer is option c.

How many timnes does 43 go into 93
Charra [1.4K]

43 can fit into 93 two whole times.

After that, there's only room for another 7 inside the 93,
so there's no way to stuff the whole 43 in there again.
