Suppose that det(a) = a b c d e f g h i = 2 and find the determinant of the given matrix. a b c −4d −4e −4f a + g b + h c + i

zhuklara [117]

I'll go out on a limb and suppose you're given the matrix

$\mathbf A=\begin{bmatrix}a&b&c\\d&e&f\\g&h&i\end{bmatrix}$

and you're asked to find the determinant of $\mathbf B$ , where

$\mathbf B=\begin{bmatrix}a&b&c\\-4d&-4e&-4f\\a+g&b+h&c+i\end{bmatrix}$

and given that $\det\mathbf A=2$ .

There are two properties of the determinant that come into play here:

(1) Whenever a single row/column is scaled by a constant $k$ , then the determinant of the matrix is scaled by that same constant;

(2) Adding/subtracting rows does not change the value of the determinant.

Taken together, we have that

$\det\mathbf B=-4\det\mathbf A=-8$

3х + 9 = 2х + 5 is it no solutions, all real numbers, or does x equal something?

zepelin [54]

Answer:

Step-by-step explanation:

<h3>Given Equation:</h3>

3x + 9 = 2x + 5

<h3>Question:</h3>

Whether x has one solution or infinite solutions or no solutions?

<h3>Solution:</h3>

=> 3x + 9 = 2x + 5

(On shifting like terms to one side we get)

=> 3x - 2x = 5 - 9

(On subtracting)

=> x = - 4

<h3>Result:</h3>

Hence, x has only one solution that is, x = -4 (Ans)

Describe how to transform the quantity of the third root of x to the fourth power, to the fifth power into an expression with a

Novosadov [1.4K]

Answer:

$x^{\frac{20}{3} }$

Step-by-step explanation:

To write: third root of x to the fourth power, to the fifth power into an expression with a rational exponent

Solution:

Exponent refers to the number of times a number is multiplied to itself.

Exponent is sometimes also known as power.

Third roots of $x=x^{\frac{1}{3} }$

Third root of x to the fourth power $(x^{\frac{1}{3} })^4 =x^{\frac{4}{3} }$

Third root of x to the fourth power, to the fifth power $=(x^{\frac{4}{3} })^5= x^{\frac{20}{3} }$
