Answer:
The approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
Step-by-step explanation:
The formula for D, the difference in temperature between the pan and the room after t minutes is:

Compute the approximate difference in temperature between the pan and the room after 9 minutes as follows:


Then the approximate temperature of the pan after it has been away from the heat for 9 minutes is:
D = P - R
206.59 = P - 69
P = 206.59 + 69
P = 275.59°F
Thus, the approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
Answer:
d =32
Step-by-step explanation:

If the cell phone company charges a flat $40 fee monthly, then the equation would be y = 40.
The company does charge $40 a month, but also charges $2 per minute out of service area (x).
So the equation is y = 2x + 40
To graph this linear function, plug in values for x then plot the plots. Then draw a line to connect the points.
y = f(x)
f(0) = 40
f(1) = 42
f(2) = 44
f(3) = 46
f(4) = 48
f(5) = 50
So at x=0, draw a point at y=40 and so on.
