Answer:

The following are the answer:

In option a  "No".

In option b  "Yes".

Step-by-step explanation:

In choice a:

Ax = 0 has no nontrivial solution. A would be the three-pivot matrix, it may assume, that the function has no free variable, and only if the function has had at least one free factor are their nontrivial formulas for the equations of the form Ax=0.  

It implies that since A is a 3x3 matrix, has no free variables so that it has no non-trivial choices, and Ax = 0.

In choice b:

we assume that every potential has at least one solution that is Ax=b . If A does have a three-pivot matrix, It will be a pivot element for each row and column, and for each possible b∈ R³, Ax = b has at least one solution.

ALOT OF POINTS IF YOU HELP ME PLEASE EXPLAIN ​
Svetllana [295]

Answer:

Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).

Step-by-step explanation:

Misha's group was asked to write an expression equivalent to  

7y²z + 3yz² - 3

When Mr. Chen checked their answers, he found only one to be correct.

And she was Helena.

Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).  

Because, (7y²z + 6yz²- 5 - 3yz² + 2)

= 7y²z + (6yz² - 3yz²) - (5 - 2)  

= 7y²z + 3yz² - 3 (Answer)

Roster method of A = {x | x is an odd number and 20 < x < 30}
Sunny_sXe [5.5K]

A "roster" here is essentially a version of the set with all of elements listed out. Here, those elements are all of the odd numbers between 20 and 30, so our list would be

{21, 23, 25, 27, 29}

37-(-3)squared+30\(-3)x2
vampirchik [111]
Simplify: 
37 - (-3)^2  + 30/(-3)x^2
= 37 +  - 9 +  - 10x^2

Combine like terms:
= 37 +  - 9 +  - 10x^2
= ( - 10x^2) + (37 +   - 90
= - 10X^2 + 28
Answer: - 10x^2  +  28



To Factor: 
37 - (- 3)^2 + 30/- 3x^2

- 10x^2 + 28
- 2(5x^2 - 14)

Answer:  - 2(5x^2 - 14)




I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -





Hope that helps!!!!

Please answer ASAP will mark brainliest if correct
Mekhanik [1.2K]

Answer:

3, 5, 7

Step-by-step explanation:

As per triangle inequality theorem:

  • <em>Any side of a triangle must be shorter than the other two sides added together</em>

Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5

  • Then 1+3< 5 and it is against the above rule, so this is not correct

The next triple is: 3, 5 and 7

  • Then 3+ 5 > 7 and it is correct

So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle
