What's the question, I'll edit my answer btw once you tell me.
Answer:-2
Step-by-step explanation:x=-2
Answer:
choose the first
Step-by-step explanation:
When h=0, T is the highest (because the temperature is highest at noon)
And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.
Answer:
-252.87 °C
Step-by-step explanation:
The problem statement tells us ...
boiling point - melting point = 6.47 °C
boiling point - (-259.34 °C) = 6.47 °C . . . . . fill in given information
boiling point = 6.47 °C - 259.34 °C . . . . . . subtract -259.34 °C
boiling point = -252.87 °C
The system of equations representing the number of Blue-ray discs and DVD's after t months are:
507 + 26t
925 - 12t
Each month, the number of DVD's sold decreases by 12, this can be modelled as:
number of DVD in opening month - (monthly decrease x number of months)
Number of DVD's in t months = 925 - 12t
Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:
number of blue-ray discs in opening month + (monthly increase x number of months)
Number of Blue-ray discs in t months = 507 + 26t
