Jen take x hours.
Carl (x-3)hours.
Jen+carl take two hours;
This means;
In 1 hour, for they work
=
=
Working together, they take two hours;
Take reciprocal of above equation and equate to two;
=
-3x=4x-6
-x-6x+6=0
x(x-1)-6(x-1)=0
(x-6)(x-1)=0
Take the bracket x-6=0 so that Carl works positive hours
x-6=0
x=6
Answer:
The statement is incorrect because an inverse relationship between y and x would imply that the graph would be a downward curved graph whose slope changes rather than linear which has constant slope (see image).
Best to express this situation as:
There is a linear relationship between y and x with a negative constant slope. The keyword here is constant since the slope is the same in a linear relationship
Step-by-step explanation:
An inverse relationship exists between y and x when y is proportional to the reciprocal of y
This would be expressed in the form 
∝ 
As x decreases , y increases or vice-versa. It is often expressed in equation form as 
or 
where k is a constant and whose graph is curved in nature. The slope is changing for the range of x values not constant as would be the case for a linear graph
All we can say about the data is that there is a linear relationship between y and x with a negative constant slope
i think you meant 42 divided by 966 but if it true, then its 1/23 in exact form but in decimal, its 0.04347826

hope this helps :)
Answer:
growth rate = 0.1733 per day, or 17.33% per day
Step-by-step explanation:
Since the doubling time is 4 days, the growth factor over a period of t days is ...
2^(t/4)
Then the growth factor for 1 day is
2^(1/4) ≈ 1.189207
The instantaneous growth rate is the natural log of this:
ln(1.189207) ≈ 0.1733 . . . per day
