Which of these expressions demonstrates the identity property? Check all that apply. 25(0) = 25
25(1) = 25
25 + 0 = 25
25 +1 = 25

25(1) = 25

25 + 0 = 25

Step-by-step explanation:

The identity property for addition is 0 because 0 added to any number is the number itself.

The identity property for multiplication is the number 1 because  1 times any number is the number itself.

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
