Answer:
-40 < F < 284
Step-by-step explanation:
* Lets explain how to solve the problem
- The range of the antifreeze protect the car between
-40°C and 140°C
- The formula of converting Celsius temperature to Fahrenheit
temperature is C = 5/9 (F - 32)
- Lets find F in terms of C
∵ C = 5/9 (F - 32)
- Multiply each side by 9/5
∴ 9/5 C = F - 32
- Add 32 to both sides
∴ 9/5 C + 32 = F
∴ F = 9/5 C + 32
- Lets find the range of the antifreeze protects the car in
Fahrenheit temperature
∵ C = -40
∴ F = 9/5 (-40) + 32 = -40
∵ C = 140
∴ F = 9/5 (140) + 32 = 284
∴ The range is between -40°F and 284°F
∴ -40 < F < 284
Let
x-------> the length side of the original cube
we have
Divide by both sides
The system of equations is equal to
--------> equation
--------> equation
using a graphing tool
see the attached figure
we know that
the solution of the system of equations is the intersection both graphs
therefore
the solution is
therefore
<u>the answer is</u>
