Answer:
D b = -2E +212
Step-by-step explanation:
The slope is given by -2 for every 1000 ft
The initial value is 212 degrees
We can use
y = mx+b where m is the slope and b is the initial value
y = -2x +212
We are at an elevation of E thousand ft
Replace x with E
y = -2 *E +212
b is the boiling point at this elevation
We replace y with b
b = -2E +212
The value of 2 in 2,783 is thousand. The value of 2 in 7,283, is hundred.
So it is one times the value.

-4^4 = four to the fourth power = (-4)(-4)(-4)(-4) = 256
Remember, when a negative is multiplied by a negative it equals a positive.
The equasion has only one solution.
