⇒ 
⇒
Hence, it is proved that . (Answer)
Answer:
Option A is correct.
Step-by-step explanation:
Given equation is 3x + 4y + 6z = 12
We have to find ordered triplet which indicate where the plane cuts the x-axis.
To find x-coordinate where plane cuts the x-axis we put y and z equal to 0.
3x + 4 × 0 + 6 × 0 = 12
3x + 0 + 0 = 12
3x = 12
x = 4
So, the coordinate where it cuts x-axis is ( 4 , 0 , 0 )
Therefore, Option A is correct.

Answer:
7 and 6 respectively
Step-by-step explanation:
Firstly, we have to solve the equations simultaneously.
2x + 7p = 56
3x - 11p = -45
Multiply equation I by 3 and ii by 2
6x +21p = 168
6x - 22p = -90
Subtract the second from first to yield:
43p = 258
p = 6
Insert this in equation 1 where we have 2x + 7p = 56
2x + 7(6) =56
2x + 42 = 56
2x = 14 and x = 7
The equilibrium price is 6 and the equilibrium quantity is 7
