A section of a hot water heating system must be suspended. The section is made from one-inch copper tubing weighing 12.167 pounds. The water inside the tubing weighs 7.6734 pounds. What is the total weight that must be
supported in this section?
Select one:
a. 17.3467
b. 20.7843
c. 19.8404
d. 22.8263

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
