The distributive law requires

The Distributive Law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

Step-by-step explanation:

Example:  "3" can be "distributed" across the "2+4" into 3 times 2 and 3 times 4.

problem:

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

f(5/2) = 10/3

i hope this !
