Given:

The graph of system of inequalities.

To find:

The system of inequalities.

Solution:

From the given graph it is clear that the shaded region is lies below the line y=10 and the boundary line y=10 is a solid line. So, the sign of inequality must be .

.

The shaded region lies on the right side of the y-axis. So, .

Another boundary line passes through the point (0,1) and (1,2). So, the equation of the line is:

The boundary line is a dotted line and the shaded region lies above the boundary line, so the sign of inequality must be .

So, the required system of inequalities is:

Therefore, the correct option is B.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
