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
Therefore the required result is 9x-2y =0.

Answer:
Step-by-step explanation:
1,480 is a lot of tiles. Did you mean 80 tiles?
30 cm = 0.3 m
Area of one tile = 0.3² m² = 0.09 m²
Multiply the number of tiles by 0.09 m².
D. 75 cm
Step-by-step explanation:
fill in the y with 20.5, so you get 20.5=0.3x-2. Add the 2 to the 20.5 so you get 22.5=0.3x. Divide both by 0.3 to get 75=x.
sorry if it's a bd explanation, hope this helps :)
Answer:
2nd option
Step-by-step explanation:
The zeros are the points on the x- axis where the graph crosses.
Since the graph crosses the x- axis at x = - 1 and x = 5, then
The zeros are x = - 1 and x = 5
