Question

Graphic solve the system of linear equations 3x+y <_ 66000, x+y <-45000

Answer 1

Answer:

3 x + y ≤ 66,000

x + y < -45,000

Plotting these inequalities on the graph

when solved these two inequalities on the graph their point of intersection is (55,500, -100500).

Colored area occupied by both the inequality,Red representing first, and blue representing Second, and found that

All the points  on the left of inequality , x+y≤ -45,000 , such that , x ∈ (-∞, 55500) is the solution of the inequality.
