Elementary Algebra problems
- 1. The shaded region represents
Options- A. y ? x
- B. y ? ? x
- C. y ? x
- D. y ? ? x Discuss
Correct Answer: y ? x
Explanation:
The shaded region represents
y ? x
- 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
Options- A. a + b + c
- B. 0
- C. 4 (a + b + c)
- D. 3 abc Discuss
Correct Answer: 0
Explanation:
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 .
