Answer:

<K is smaller then <X, making JL less then WY

Step-by-step explanation:

Answer:

a) ∝A ∈ W

so by subspace, W is subspace of 3 × 3 matrix

b) therefore Basis of W is

={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}

Step-by-step explanation:

Given the data in the question;

W = { A| Air Skew symmetric matrix}

= {A | A = -A^T }

A ; O⁻ = -O⁻^T        O⁻ : Zero mstrix

O⁻ ∈ W

now let A, B ∈ W

A = -A^T       B = -B^T

(A+B)^T = A^T + B^T

= -A - B

- ( A + B )

⇒ A + B = -( A + B)^T

∴ A + B ∈ W.

∝ ∈ | R

(∝.A)^T = ∝A^T

= ∝( -A)

= -( ∝A)

(∝A) = -( ∝A)^T

∴ ∝A ∈ W

so by subspace, W is subspace of 3 × 3 matrix

A ∈ W

A = -AT

A = [tex]\left[\begin{array}{ccc}o&a&b\\-a&o&c\\-b&-c&0\end{array}\right][/tex]

= [tex]a\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex]+b\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex]+c\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]

therefore Basis of W is

={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}

Step-by-step explanation:

I think this may be the answer that is if you are to change the equations to subtraction problems, I can't see the picture so it's hard to answer.

Have a great day!

Step-by-step explanation:

Answer:

Options (2) and (3)

Step-by-step explanation:

Slope of line segment is given by the formula,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

Here, the line given in the graph has the Rise as negative (Since, segment is slanting down) and Run as positive.

Therefore, slope of the segment is negative which describes that the function is decreasing in the interval 2.

Options (2) and (3) will be the correct options.

Answer:

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

Step-by-step explanation:

We can simply observe the sums to conclude that the sum will be positive or negative.

A. –5 + (–2)

We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.

-5+(-2) = -5-2 = -7

B. 5 + (–2)

The number with greater magnitude is positive so the sum will also be positive.

5 + (–2) = 5-2 = 3

C. –3 + 4

The number with greater magnitude is positive so the sum will also be positive.

-3+4 = 1

D. 0 + (–3)

The number with greater magnitude is negative so the sum will also be negative.

= 0-3 = -3

E. –2 + 4

The number with greater magnitude is positive so the sum will also be positive.

-2+4 = 2

Hence,

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

Answer:

There is no question.

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\frac{5x - 2}{4}+\frac{1}{2}=\frac{3y+2}{2}[/tex]

Multiply the equation by 4

[tex]4*\frac{5x - 2}{4}+4*\frac{1}{2}=4*\frac{3y+2}{2}\\[/tex]

5x - 2 + 2 = 2*(3y + 2)

5x +0 = 2*3y + 2*2

5x = 6y + 4

5x - 6y = 4 --------------------(I)

[tex]\frac{7y+3}{3}=\frac{x}{2}+\frac{7}{3}\\[/tex]

Multiply the equation by 6

[tex]6*\frac{7y+3}{3}=6*\frac{x}{2}+6*\frac{7}{3}\\[/tex]

2*(7y + 3) = 3x + 2*7

14y + 6 = 3x + 14

14y = 3x + 14 - 6

14y = 3x + 8

-3x + 14y = 8 ------------------------(II)

Multiply equation (I) by 3 and equation (II) by 5 and then add

(I)*3              15x - 18y = 12

(II)*5           -15x  + 70y = 40     {Now add}

                          52y = 52

                              y = 52/52

                            y = 1

Substitute y =1 in equation (I)

5x - 6*1 =  4

5x - 6 = 4

      5x = 4 +6

      5x = 10

         x = 10/5

x = 2

Answer:

a function is :a relation from the set of inputs to a set of possible outputs where each input is related o exactly one output

Answer:

16 - 6n

Step-by-step explanation:

10 , 4 , -2 , - 8 .....

This is arithmetic sequence

first term = 10

Common difference = 2nd term - first term

                          d    = 4 - 10

                            d = -6

nth term = a₁ + (n -1)d

              = 10 + (n - 1)*(-6)

             = 10 + n*(-6) - 1*(-6)

             = 10 - 6n + 6

             = 10 + 6 - 6n

             = 16 - 6n
