Give an example of a 2x2 matrix without any real eigenvalues:___________
9966 [12]

Answer:

Step-by-step explanation:

An eigenvalue of n × n is a function of a scalar \lambda  considering that there is a solution (i.e. nontrivial) to an eigenvector x of Ax =  

Suppose the matrix A = \left[\begin{array}{cc}-1&-1\\2&1\\ \end{array}\right]

Thus, the equation of the determinant (A - \lambda1) = 0

This implies that:

\left[\begin{array}{cc}-1-\lambda &-1\\2&1- \lambda\\ \end{array}\right] =0

-(1 - \lambda^2 ) + 2 = 0

-1 + \lambda ^2 + 2= 0

\lambda^2 +1 =0

Hence, the eigenvalues of the equation are \mathtt{\lambda = i , -i}

Also, the eigenvalues can be said to be complex numbers.

1<br> —<br> 3<br> (9x + 3) = 3x + 1
Hatshy [7]

Answer: x = -0.3

Step-by-step explanation:

<u>Given expression</u>

1 - 3 (9x + 3) = 3x + 1

<u>Expand parentheses and apply the distributive property</u>

1 - 27x - 9 = 3x + 1

<u>Combine like terms</u>

(1 - 9) - 27x = 3x + 1

-8 - 27x = 3x + 1

<u>Subtract 3x on both sides</u>

-8 - 27x - 3x = 3x + 1 - 3x

-8 - 30x = 1

<u>Add 8 on both sides</u>

-8 - 30x + 8 = 1 + 8

-30x = 9

<u>Divide - 30 on both sides</u>

(-30)x / (-30) = 9 / (-30)

(-30)x / (-30) = 3 / (-10)

\boxed{x=-0.3}

Hope this helps!! :)

What is the perimeter of rectangle J K L M
Nostrana [21]

Step-by-step explanation:

you could count the squares around the shape or you could do it by points

For example point M is (2,3)

L is (6,3)

We want to find the length of this side so we subtract the x values

6 - 2 = 4 units

that gives use the length of that leg and since a rectangle is symmetrical, you can just measure 2 sides

If Neal and Linda had a combined taxable income of $209,150 and filed their federal income tax with the married filing jointly s
Yuki888 [10]

Answer:

correct option is A. $46840.50

Step-by-step explanation:

given data

taxable income = $209,150

solution

we calculate the tax for income is $209,150

The tax of the taxable income over $208,850 but but not over $372950 is

tax of the taxable income over $208,850 =  $47741.50  plus 33% of the amount over $208850

tax = $47741.50 + 33% of ( $209,150 - $208850  )

tax = $47741.50 + 33% of ( $300)

solve it we get

tax = $46840.5

so correct option is A. $46840.50
