47 deg F
15° F is 10 degrees cooler than 25° F.
40F is colder because it is only 8F above freezing point of water and 40C is warmer because it is it is about 3C higher than the human body temperature. 40F = (40 - 32) x 5/9 = 4.4444 degrees C 40C = (40 x 9/5) + 32 = 104 degrees F
To find ( f(x) ) when ( x = -5 ), substitute (-5) into the function ( f(x) = 5x + 40 ). This gives: [ f(-5) = 5(-5) + 40 = -25 + 40 = 15. ] Thus, ( f(-5) = 15 ).

Yes, 34°F is colder than 40°F. On the Fahrenheit scale, lower numbers indicate colder temperatures, so 34°F is 6 degrees cooler than 40°F.
-40 is the only temperature where F and C are exactly the same. Neither one is colder.
47 deg F
40 degrees fahrenheit is about 4.4 degrees celsius, while 10 celsius is 50 degrees fahrenheit so 40 fahrenheit is the colder temperature. The formulas to convert between celsius and fahrenheit temperatures (where F is the Fahrenheit temperature and C is the Celsius temperature in degrees) are as follows: Celsius to Fahrenheit: F = C × 9/5 + 32 Fahrenheit to Celsius: C = (F − 32) x 5/9
15° F is 10 degrees cooler than 25° F.
Yes, assuming that your refrigerator is set at 40°F. or colder.

40F is colder because it is only 8F above freezing point of water and 40C is warmer because it is it is about 3C higher than the human body temperature. 40F = (40 - 32) x 5/9 = 4.4444 degrees C 40C = (40 x 9/5) + 32 = 104 degrees F
No F = 9/5 C + 32 = 1.8(20) + 32 = 68F which is warmer than 40F
-80°F is colder than -47°F.
To find ( f(x) ) when ( x = -5 ), substitute (-5) into the function ( f(x) = 5x + 40 ). This gives: [ f(-5) = 5(-5) + 40 = -25 + 40 = 15. ] Thus, ( f(-5) = 15 ).
-6 Fahrenheit is colder. It is below zero.
