What is the difference between associative and commutative property?
make sure to give examples of how they are

Step-by-step explanation:

The difference between associative and commutative property is that:

a} In Associative property numbers can be grouped in any way and yet the answer will be same.

Ex 1; (2+3)+2 or (2+2)+3 gives the same result i.e.

Ex 2; (2*3)+2 or (2+2)*3 gives the same result i.e. 12

b} In Commutative property numbers can be arranged in any order yet the result is same

Ex 1; 2+6+1 or 1+2+6 gives the same result i.e. 9

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 !
