Question

Name the property the equation illustrates.
-2.1*1+ -2.1

Answer 1

IS IT Identity Property of Multiplication
OR
Inverse Property of Multiplication

Answer 2

Is that suppose to be $$-2.1*1= -2.1$$ not -2.1*1+ -2.1

Answer 3

NO ITS RIGHT HOW I PUT IT
-2.1x1=-2.1

Answer 4

I gave you like all the propertied yesterday.

Answer 7

Commutative Property of Addition
a + b = b + a

ex:) 2 + 3 = 3 + 2

Answer 8

Commutative Property of Multiplication
a • b = b • a

ex:) 2 • ( 3 ) = 3 • ( 2 )

Answer 9

Associative Property of Addition
a + ( b + c ) = ( a + b ) + c

ex:) 2 + ( 3 + 4 ) = ( 2 + 3 ) + 4

Answer 10

Associative Property of Multiplication
a • ( b • c ) = ( a • b ) • c

ex:) 2 • ( 3 • 4 ) = ( 2 • 3 ) • 4

Answer 11

Distributive Property
a • ( b + c ) = a • b + a • c

ex:) 2 • ( 3 + 4 ) = 2 • 3 + 2 • 4

Answer 12

Additive Identity Property
a + 0 = a

ex:) 3 + 0 = 3

Answer 13

Multiplicative Identity Property
a • 1 = a

ex:) 3 • 1 = 3

Answer 14

Additive Inverse Property
a + ( -a ) = 0

ex:) 3 + (-3) = 0

Answer 15

Zero Property
a • 0 = 0

ex:) 5 • 0 = 0

Answer 16

@anaivillegas This is what you posed as a question:

Name the property the equation illustrates.
-2.1*1+ -2.1

Answer 17

This is not an "equation," can you tell me why?

Answer 18

First she said: -2.1*1+ -2.1

Then: -2.1x1=-2.1

Answer 19

srry @skullpatrol

Answer 20

yeah I see @skullpatrol haha poor you :( lol

Answer 21

lol

Answer 22

Identity Property of Multiplication:

There is a unique real number 1
such that for every real number a,
a*1=a and 1*a=a.

Answer 23

Replace "a" with the real number -2.1

Answer 24

or look at my example :)
