To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.

Answer:
Capacity of 60000 litres "to 1 significant figure" means that lower bound is 54449, upper bound is 64999.
=> 10% of that capacity is more than 54449/10 = 5444.9 litres
Tony pours in 5400 litres of water "to 2 significant figure" means that lower bound is 5349, upper bound is 5444.
Because 5444<5444.9, then clearly he is not correct when he said " I have filled more than 10% of the container"
Answer: n= -20?
Step-by-step:
Simplify both sides of the equation
1/5n+4=0
Then subtract 4 from both sides
1/5n + 4 - 4 = 0 - 4
1/5n= -4
Then multiply both sides by 5
5*(1/5n)=5*(-4)
