Afamily’s well pumps water into a tank at a rate of 10 gal/min. in the morning, the tank has 1700 gal. which equation models the amount of water y in the tank after the well pumps for x min?
a. y=-10x-1700
b. y= -10x + 1700
c. y= 10x + 1700
d. y= 10x - 1700

I would say the answer is D. Y=10x -1700. I think this because if you do the work: which changes the value of -1700 to 1700 when switching to other side leaving the equation 1700=10x so you just divide to find your final answer which is 170 minutes to get 1700 gallons in total. I hope this helps!

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
