Ahomeowner is draining her swimming pool. the volume of water in the pool changes by −12 gallons every minute. what is the change in volume over 60 minutes?

So, water decreases by 12 gallons EVERY minute.

How much water will decrease in 60 minutes?

gallons

So, the volume changes by 720 gallons in 60 minutes.

ANSWER: Volume decreases 720 gallons in 60 minutes.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer: it's d
