Answer:
Therefore the required result is 9x-2y =0.
Step-by-step explanation:
Given equation are
x-3y =6.....(1)
-8x-y=6 .....(2)
Subtracting equation (2) from (1)
x - 3y = 6
-8x - y= 6
+ + - [ The sign of equation (2) will be change in case of
_________ subtraction and in case of plus the signs remains same ]
(x+8x)-3y+y=6-6 [ adding the like terms]
⇒9x-2y =0
what?
let h=-12, k=-11 then
(x-h)^2 + (y-k)^2= r^2
(x+12)^2 + (y+11)^2 = 7^2
x^2 + 24x + 144 + y^2 + 22y + 121 = 49
x^2 + y^2 + 24x + 22y + 144+121-49= 0
x^2 + y^2 + 24x + 22y + 216 = 0 is the required eq
Answer:12 is the mean
Step-by-step explanation: Just find the middle number
