The value of the matrix X is X =  [tex]\left[\begin{array}{ccc}-7&-2\\7&0\\\end{array}\right][/tex].

Matrices are a set of numbers arranged in such a way that the numbers are arranged in rows and columns.

Each number is called element in a matrix.

Given are two matrices.

A = [tex]\left[\begin{array}{ccc}2&-7\\6&1\\\end{array}\right][/tex] and B = [tex]\left[\begin{array}{ccc}-9&5\\1&-1\\\end{array}\right][/tex]

We have given that, a matrix X exists such that,

X - A = B

We can rearrange this as,

X = A + B

Adding the two matrices,

The entries will be,

2 - 9 = -7

-7 + 5 = -2

6 + 1 = 7

1 - 1 = 0

X =  [tex]\left[\begin{array}{ccc}-7&-2\\7&0\\\end{array}\right][/tex]

Hence the X is option A.

Answer:

If the difference of x and 22=8

then equation is

X -22=8

X=22+8

X=30

therefore now we put the value of x in the equation

30-22=8

8=8

Answer:

x would be 30

Step-by-step explanation:

x-22=8

x=8+22

x=30

Answer:

A and C

Step-by-step explanation:

20) Since the triangles are similar, you can say that 98 corresponds to 42 and 77 corresponds to 3x+6, because of this you can write an equation ((98/77)(3x-6) =42) and then simplify to get x = 13.

21) Since ABC and DFE are similar, we can say that 2x+2 corresponds to x+3 and 24 corresponds to 16. You can write this as the equation (24/2x+2)(x+3) = 16 and simplify to get x=5.

Answer:

√130 or ≈ 11.40175425

Step-by-step explanation:

(-6, 0) & (5, 3)

To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the given values.

d = √[(5 - (-6))² + (3 - 0)²]

Simplify the parentheses.

d = √[(5 + 6)² + (3 - 0)²]

d = √[(11)² + (3)²]

Evaluate the exponents.

d = √[(121) + (9)]

Add the expression within the brackets [ ].

d = √[130]

This is your answer.

√130

or

≈ 11.40175425

Answer:

The number is -5

Step-by-step explanation:

Equation: 8(7+x) = 16

I got

[tex]0.75 + 2\pi \times n[/tex]

[tex]5.28 + 2\pi \times n[/tex]

[tex]1 + 2\pi \times n[/tex]

5.53+2pi times n

WORK:

[tex](3 \sin(2x) + 3 \cos(2x) )) {}^{2} = 9[/tex]

[tex] \sin(2x) + \cos(2x) {}^{2} = 3[/tex]

[tex] \sin(x) + \cos(4 {x}^{2} ) = 3[/tex]

[tex]4 {x}^{2} + x = 3[/tex]

[tex]4 {x}^{2} + x - 3 = 0[/tex]

[tex](4x {}^{2} + 4x - 3x - 3 = 0[/tex]

[tex]4x(x + 1) - 3(x + 1) = 0[/tex]

[tex](4x - 3)(x + 1)[/tex]

Solve for x

[tex]4x - 3 = 0[/tex]

[tex]4x = 3[/tex]

[tex]x = \frac{3}{4} [/tex]

[tex]x + 1 = 0[/tex]

[tex]x = - 1[/tex]

While -1 is a solution, it isn't within the interval of 0,2pi.

However, we can use the reference angle identity

[tex] \cos(x) = \cos(x + 2\pi) [/tex]

So some more possible points are

[tex] - 1 + 2\pi[/tex]

Since it on a interval, it must be less than 2 pi or 6.28.

Let find some more points

[tex] - 1 + 2\pi = 5.28[/tex]

So 5.28 is a point,

[tex] \frac{3}{4} + 2\pi = 7.03[/tex]

That is too big since -6.28 is smaller than 7.03

We can use the identity

[tex] \cos(x) = \cos( - x) [/tex]

[tex] \cos( - 1) = \cos( 1 ) [/tex]

1 is smaller than 2pi so it is true.

[tex] \cos( \frac{3}{4} ) = \cos( - \frac{3}{4} ) [/tex]

Negative 3/4 is smaller than zero so it not a solution.

[tex]0.75[/tex]

[tex]5.28[/tex]

[tex] 1[/tex]

Make sure to include

[tex]2\pi \times n[/tex]

so

[tex]0.75 + 2\pi \times n[/tex]

[tex]5.28 + 2\pi \times n[/tex]

[tex]1 + 2\pi \times n[/tex]

We can also -3/4 plus 2 pi.

Answer:

43

Step-by-step explanation:

angle sum property of quadrilateral

87+ 103 + 127+ x = 360

317 + x = 360

x= 360-317

x = 43

Answer:

The number that goes in place of the question mark is 2.

Step-by-step explanation:

Let's solve it!

3x² + 12x - 24 = 0

First we can factor 3 out of each term:

x² + 4x - 8 = 0

Now we'll add 12 to both sides to complete the square:

x² + 4x + 4 = 12

And finish it off:

(x + 2)² = 12

So the answer to the question is 2

Bonus:

We can also now solve this for x:

(x + 2)² = 12

x = √12 - 2

x = 2√3 - 2

x ≈ 2 × ±1.732 - 2

x ≈ 1.464, -5.464

Answer:

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
