Closure Property(Integers)

1. Addition : Adding two integers gives an Integer, so Integer satisfy closure property.For example

  2+3=5

2 and 3 are integers,so 2+3=5 , will be also an integer.

2.Subtraction : Subtracting an integer from another one yields an integer.So, Integer satisfy closure property with respect to Subtraction.

For example

  2-3=-1

2 and 3 are integers,so 2-3= -1 , will be also an integer.

3.Multiplication: Multiplication of an Intreger with another integer result in an integer.So, Integer satisfy closure property with respect to Multiplication.

 For example

  2×3=6

2 and 3 are integers,so 2×3=6 , will be also an integer.

4.

Integers are not closed under divison.Because

   \rightarrow \frac{a}{b}\neq \frac{b}{a}\\\\\frac{2}{3}\neq \frac{3}{2}

<h2><u><em>x = - 14</em></u></h2>

Step-by-step explanation:

-3x – 10 = 32 Help me I need the answer

-3x – 10 = 32

-3x = 32 + 10

-3x = 42

x = 42 :(-3)

x = - 14

-----------------

check

-3 × (-14) - 10 = 32                      (remember pemdas)

42 - 10 = 32

32 = 32

Which of the following is an example of the atmosphere interacting with the biosphere?
Vilka [71]

I’d say option 4

However, one may think option 3 might be possible as well. But that it is not interacting, it’s affecting.

So I’d stick with option 4.

Good luck!
