Which property is shown in the matrix addition below?<br> [-6 15 -2 ] + [6 -15 2 ] = [0 0 0

aksik [14]

Answer:

The property shown in matrix addition given is "Additive Inverse Property"

Step-by-step explanation:

First of all lets define what a matrix is.

A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.

There are several addition properties for matrices.

One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.

Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.

$\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right]$

Hence,

The property shown in matrix addition given is "Additive Inverse Property"

I need help on c and d please

Dennis_Churaev [7]

A

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.

The conjecture is that x = a + b. You should always find that to be true. C is the clincher.

Here's how you do that.

x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o

Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o

So we have two conditions that equal 180o. Equalities can be equated to one another.

a + b + c = x + c Subtract c from both sides.

a + b = x.

Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.

Summary

a cannot be solved without 28

b you should say that the two remote angles (a and b) will always total x

c The proof is provided for you.

Pls help find the value of x

irinina [24]

I think the answer is 95
Explanation = first add 100 with 45 you will get 195 then subtract 180 with 195 then you will get 95. 95 is the answer
