Answer:

The solution of the system of inequalities 3x > y and x + y ≤ 4 is graphed by the shaded region given.

Explanation:

See the graph attached.

The dotted straight line passes through the points (0,0) and (3,1).

Therefore, the equation is
(y - 0)/(0 - 1) = (x - 0)/(0 - 3) {Using the two point form of equation of straight line}

⇒ 3y = x ........ (1)

Therefore, the shaded part of the graph holds the equation 3y > x {AS the shaded portion does not include the straight line (1)}

Again, the equation of the firm line is given by
(x)/(4) + (y)/(4) = 1 {Applying the intercept form of equation of straight line}

⇒ x + y = 4 ......... (2)

Therefore, the shaded region of the graph is represented by the equation x + y ≤ 4 {Since, the shaded region includes the line also}

Therefore, the solution of the system of inequalities 3x > y and x + y ≤ 4 is graphed by the shaded region given. (Answer)
