So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
12 inch bucket fills half an inch every 10 mins
20 mins is 1 inch
40 mins is 2 inch
60 mins is 3 inch
80 mins is 4 inch
100 mins is 5 inch
120 mins is 60 inch and 6 inch is half of 12 so
double 120 to get 240 which is 4 hours
Rotation and reflection are instances of transformation
See attachment for the new position of 
From the question, we have:
The rule of 90 degrees clockwise rotation is:
Using the above transformation, the new points would be
The next transformation is reflection over the x-axis
The rule of this transformation is:
So, the new points would be:

Answer:
x = -8/b
Step-by-step explanation:
2bx-bx= -8
bx = -8
Divide by b since b is nonzero
x = -8/b
Set the 2x - 1 equal to 9 then work backwards. 2x - 1 = 9 Nine minus one is eight divided by two is four. X = 4
