Answer:
the midpoint would be (5,9)
Answer: He was killed 24.83 hours before the body was found.
Step-by-step explanation:
Since we have given that

Here, T is the temperature of a body t hr after death, T = 82°F
T₀ is the air temperature , T₀ = 67°F
T₁ is the body temperature at the time of death = T₁ = 98.6°F
So, we will substitute all the values in the above equation.

Hence, he was killed 24.83 hours before the body was found.
Well, just solve the equation
-70 =

-70 =

-70 - 2 = 36a
a = -72/36 = -2
Multiplication and division are inverse operations.
If you start with a number and divide it and multiply it by the same number (not zero), you get the original number back.
Since you want to undo a division by 7, you must multiply by 7.
Answer: A. Multiplying by 7
