For the sum we have the following properties:
The properties are commutative, asosiative, distributive and neutral element.
Commutative property: When two numbers are added, the result is the same regardless of the order of the addends.
Associative property: When three or more numbers are added, the result is the same regardless of the order in which the addends are added.
Neutral element: The sum of any number and zero is equal to the original number.
Distributive property: The sum of two numbers multiplied by a third number is equal to the sum of each summand multiplied by the third number.<span><span>
</span><span>For subtraction we have:
</span><span> The arithmetic operation of the subtraction (subtraction) is indicated by the minus sign (-) and is the opposite, or inverse, operation of the addition. </span><span>That is, it is an arithmetic operation that serves to find the difference between two numbers.
</span><span>
In subtraction A - B = D
</span><span>A is the minuendo
</span><span>B is the substraendo
</span><span>D is the difference
</span><span>Answer:
</span><span>The properties of addition and subtraction serve to rewrite and simplify calculations.</span></span>
The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10) = -1
slope is -1.
That value would be written as 36,214.009
Answer: y = 32/7
Step-by-step explanation:
Solve the first equation for x by subtracting the 2y from the left side and getting: x = 1 - 2y.
Plug this in to the second equation: 2(1 - 2y) - 3y = -30 → 2 - 4y - 3y = -30 →
-7y = -32 → y = 32/7. Hope this helps!
