Answer:
The water level is falling.
The initial level of water in the pool was 3,500 units
The water was 2,600 units high after 4 hours.
Step-by-step explanation:
The given function that models the water level is
where represents time in hours.
The function represents a straight line that has slope
Since the slope is negative, it means the water level is falling.
The initial level of water in the pool can found when we put into the function.
, hence the initial level is 3,500.
To determine the level of water in the pool after 14 hours, we put into the equation to get;
To determine the water level after 4 hours we put
Answer:
Step-by-step explanation:
step 1
Find the slope of the given line
we have
isolate the variable y
The slope of the given line is
step 2
Find the equation of the line that goes through the point (1,5) and is parallel to the given line
Remember that
If two lines are parallel then their slopes are equal
therefore
we have
substitute in the equation of a line in slope intercept form
solve for b
substitute
