Water is draining from a tank. The graph of f(x), the amount of water in the tank in gallons, as a linear function of x, the number of hours water has been draining, passes through the points (20, 0) and (0, 80). What is the rate of change in f(x) with respect to x?

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side

the circumference is c≈245.04
