The function F is defined by F(x)= 12/x + 1/2 Use this formula to
find the following values of the function:
F(k)
F(a/2)
F(x-1)
F(2x+3)
F(x+h)

F(2x+3) = 12/(2x+3) +1/2

Step-by-step explanation:

Put the argument of the function where the variable is. You can simplify if you want, but the original function definition is not simplified, so we assume it is not required.

F(x) = 12/x + 1/2

Put (2x+3) where x is:

F(2x+3) = 12/(2x+3) + 1/2

1/5x+9 2/5y+7

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
