Question 1

The shaded region represents

Accepted Answer

The shaded region represents y ≤ x

Question 2

If x = a – b, y = b – c, z = c – a, then the numerical value of the algebraic expression x3 + y + z – 3xyz will be

Accepted Answer

Here , x = a – b, y = b – c, z = c – a We have x + y + z = a – b + b – c + c – a = 0 ∴ x3 + y + z – 3xyz = 0 Hence , the numerical value of algebraic expression is 0 .
