Since the rate of filling is constant, it is a rule consisting of a linear expression.
Let H=height, and
x=number of days since today (day 0).
Since water rises 2 feet per day, today's height, H = 14 feet.
So the rule is then
H = 14+2x
where 2 = additional depth per day
14 = initial value, or today's depth.
A tank is filling with water from a natural spring. two days ago the water was 10 feet deep. yesterday the water was 12 feet deep. Assume that the water depth continues to rise at the same rate after today. How do you write this expression
