To find the difference between -5°F and 20°F, you subtract the lower temperature from the higher one: 20°F - (-5°F) = 20°F + 5°F = 25°F. Thus, the difference between -5°F and 20°F is 25°F.
5 times the function of f
Let F = Fahrenheit Let C = Celcius Let K = Kelvin F = 9/5 C +32 C = K -273 F = 9/5 (K-273) +32 F = 9/5K - 491.4 +32 SINCE F = K then F = 9/5 F - 491.4 +32 459.4 = 9/5 F - F 459.4 = 9/5 F - 5/5F = 4/5 F 459.4 = 4/5 F F = 5/4 (459.4) = 574.2
5 +1/4 f = 5 + f/4
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 ).
F(x) = 3x + 2 f(5) = 3*5 + 2 = 17

That would be the thermostat.
-i-f-?
To find ( f(4) ) for the function ( f(x) = 2x - 5 ), substitute ( x ) with 4. This gives you ( f(4) = 2(4) - 5 = 8 - 5 = 3 ). Therefore, ( f(4) ) is 3.
It is 5*f where f is an expression.
