Triangle OPQ above is the solution of the inequalities
-
A.
x + 1 ≥ 0, y + x ≤ 0, y – x ≥ 0 -
B.
y + x ≤ 0, y – x ≥ 0, x -1 ≥ 0 -
C.
x – 1 ≤ 0, y – x ≥ o, y + x ≥ 0 -
D.
x – 1 ≤ 0, y + x ≤ 0, y – x ≤ 0
Correct Answer: Option A
Explanation
Lines bounding Δ OPQ
OQ; y – x = 0
y – x ≥ 0
PQ; x + 1 = 0
x + 1 ≥ = 0
PO; y + x = 0
y + x ≤ 0
∴ x + 1 ≥ 0, y + x ≤ 0, y – x ≥ 0
