Answer:
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.
[tex]a+0=a[/tex]
Commutative property of addition: If a and b are two numbers, then
[tex]a+b=b+a[/tex]
Associative property of addition: If a, b and c are three numbers, then
[tex]a+(b+c)=(a+b)+c[/tex]
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.
[tex](a)(1)=a[/tex]
Commutative property of multiplication: If a and b are two numbers, then
[tex]ab=ba[/tex]
Associative property of multiplication: If a, b and c are three numbers, then
[tex]a(bc)=(ab)c[/tex]
