The answer is 47 minutes.
You basically imagine this: Debra has a phone card for $30. She used x minutes every 16 cents. You end up with $22.48.
30 - (0.16x) = 22.48
You can basically graph that equation and the x-intercept will show you your answer. x = 47

Answer:
if and only if the rectangle is a square
Step-by-step explanation:
The angle bisectors of a rectangle will meet at a single point if, and only if, the rectangle is a square.
In general, a rectangle does not have an incenter.
__
The incircle must be tangent to all sides of the polygon. That cannot be the case unless the rectangle has its length equal to its width. That is, it must be a square.

Step-by-step explanation:
<em>The question is incomplete as the function is not given. However, the following explanation will guide you.</em>
<em></em>
The average rate of change is calculated using;
Where
Take for instance;
The function is:
We have to solve for f(-1) and f(5);
i.e.
Substitute -1 for a and 5 for b
Substitute values for f(5) and f(-1)
<em>Apply this steps in your work</em>
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes:
We found the slope:
Substituting we have:
Thus, the equation is of the form:
We substitute one of the points and find the cut-off point:
Finally, the equation is:
