Answer from: TTHOR1935

1. -9 + 0 = -9 identity property of addition

2.(-9)(0) = (0)(-9) commutative property of multiplication

3.(-9)(1) = -9 identity property of multiplication

4.-1(4 · 9) = (-1 · 4)9 associative property of multiplication

5.-9 + 1 = 1 + (-9) commutative property of addition

6. -1 + (4 + 9) = (-1 + 4) + 9 associative property of addition

Answer from: derrishamckenzie22

Statement Property

1. -9 + 0 = -9 Identity property of addition

2. (-9)(0) = (0)(-9) Commutative property of multiplication

3. (-9)(1) = -9 Identity property of multiplication

4. -1(4 · 9) = (-1 · 4)9 Associative property of multiplication

5. -9 + 1 = 1 + (-9) Commutative property of addition

6. -1 + (4 + 9) = (-1 + 4) + 9 Associative property of addition

Step-by-step explanation:

Identity property of addition: If a is a number, then the addition of the number and identity element gives the same number. Identity element of addition is 0.

a+0=a

Commutative property of addition: If a and b are two numbers, then

a+b=b+a

Associative property of addition: If a, b and c are three numbers, then

a+(b+c)=(a+b)+c

Identity property of multiplication: If a is a number, then the product of the number and identity element gives the same number. Identity element of multiplication is 1.

(a)(1)=a

Commutative property of multiplication: If a and b are two numbers, then

ab=ba

Associative property of multiplication: If a, b and c are three numbers, then

a(bc)=(ab)c
