Question

Which graph represents the solution to the system of inequalities?

x + y ≤ 50

x ≥ 20

Answer 1

The Fourth Graph should be the graph representing the mentioned inequalities

Answer 2

Fourth graph.

Explanation:

Using demos calculator we plot the graph.

Orange Shaded area shows the equation :
`x + y\leq 50`

Blue area shows the equation:
`x\geq 20`

Refer the attached image

The solution of the equations is (20,30) and (50,0)

The fourth graph shows the same solutions.

So, Graph 4 is correct.

Hence fourth graph represents the solution to the system of inequalities.
