Subtraction is the inverse operation that "undo" multiplication.

<u>Step-by-step explanation:</u>

The effects caused by any operation can be reversed and the reversing process is called Inverse Operation. Mathematics had four major operations, they are Addition, Subtraction, Multiplication, and Division.

Addition and Multiplication are interconnected to each other so as Subtraction and Division. But Addition and Subtraction are the inverse operations. Also, Multiplication and Division are Inverse Operations.

Moreover, there are inverse properties explaining these Inverse Operations. These properties will result in an identity number. The identity number for Addition and Subtraction is 0 and for Multiplication and Division is 1.

Reflect triangle A in the line y=x

Answer:

(5,6), (3, 6) and (3, 5).

Step-by-step explanation:

If we imagine the line y = x to be a mirror , the image of each point is the same perpendicular distance to the mirror has the original point.

So the image of (6,5) = (5,6)

(6, 3) ---> ( 3, 6)

(5,3) ---> (3, 5).

Note that the coordinates are reversed in each case.

In this case the general rule for the reflection is (x, y) ---> (y, x).

The percentage of water in an unknown hydrate was determined by heating the sample and driving the water off the sample. Two ind

Bas_tet [7]

Answer:

It should be reported as 20.648%

Step-by-step explanation:

Since we have 2 different observed values hence we shall use an average of the 2 values to report the result

Thus value is $\frac{19.564+21.731}{2}=20.6475%$

As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.

Thus the result shall be 20.648%
