<h3>2. 4.9x^5 - 5x^3 + 2.3</h3><h3 /><h3>3. 78x^6 y^3 z^3</h3><h3 /><h3>4. 6x^2 + 14x - 12</h3><h3 /><h3>8. 9mnr^2 - 10m^2 + 7n - 14m^2 n</h3><h3 /><h3>9. 81x^3 y + 45 x^2 y^2 - 9xy^4</h3><h3 /><h3 /><h3 />
ANSWER:
- x – 3y = 2 ...(1)
- 2x – 6y = 6 ...(2)
On solving eq(1), we get
Plug the value of x in eq(2)
- 2x – 6(x - 2/3) = 6
- 2x – 2(x – 2) = 6
- 2x – 2x + 4 = 6
- 0 = 6 – 4
- 0 ≠ 2
So, given system of equations is not correct.
Answer:
735,130.
Step-by-step explanation:
The order of election of the 3 representatives does not matter so it is a combination.
The number of possible combinations
= 165! / 162! 3!
= (165 * 164 * 163) / (3*2*1)
= 735,130.
