At 7:00 a. m., Alicia pours a cup of tea whose temperature is 200°F. The tea starts
to cool to room temperature (72°F). At 7:02 a. m. the temperature of the tea is
197°F. At 7:15 a. m. the temperature of the tea is 179°F. Alicia will drink the tea
when its temperature is 170°F. Use exponential regression to find a model for the
temperature of the tea. When can Ella drink the tea?

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

sine

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
