Answer:

[tex]4.6\ \text{cm}[/tex]

Step-by-step explanation:

Perimeter of the pentagon = 20.5 cm

Length of 4 sides = [tex]x[/tex]

Length of the other side = 2.1 cm

Perimeter of the pentagon will be

[tex]x+x+x+x+2.1=20.5\\\Rightarrow 4x+2.1=20.5\\\Rightarrow 4x=20.5-2.1\\\Rightarrow 4x=18.4\\\Rightarrow x=\dfrac{18.4}{4}\\\Rightarrow x=4.6\ \text{cm}[/tex]

The value of [tex]x[/tex] is [tex]4.6\ \text{cm}[/tex].

Answer:

The determinant of C is zero and does not have inverse.

Step-by-step explanation:

Let [tex]C = \left[\begin{array}{ccc}2&4&6\\3&6&9\\4&8&12\end{array}\right][/tex], since it is a matrix with 3 rows and 3 columns, we can determine its determinant by the Sarrus' rule:

[tex]\det(C) = \left|\begin{array}{ccc}2&4&6\\3&6&9\\4&8&12\end{array}\right|[/tex]

[tex]\det(C) = (2)\cdot (6)\cdot (12)+(3)\cdot (8)\cdot (6)+(4)\cdot (4)\cdot (9)-(4)\cdot (6)\cdot (6)-(3)\cdot (4)\cdot (12)-(2)\cdot (8)\cdot (9)[/tex]

[tex]\det (C) = 0[/tex]

Since the determinant of C is equal to zero, then we conclude that C does not have an inverse according to the following definition of inverse matrix. That is:

[tex]C^{-1} = \frac{1}{\det(C)}\cdot adj(C)[/tex] (1)

Where [tex]adj(C)[/tex] is the adjugate matrix of C, defined as the transpose of the cofactor matrix of C.

The result of this expression is undefined due to the determinant.  

Answer:

The value of x in the triangle shown below is 5.

Step-by-step explanation:

We can use the pythagorean theorem to solve this, incase you forgot, this is the pythagorean theorem:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex]a = side \\ b = side \\ c = diagonal[/tex]

So lets solve using the pythagorean theorem.

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {12}^{2} + {b}^{2} = {13}^{2} \\ 144 + {b}^{2} = 169 \\ \frac{- 144 \: \: \: \: \: = - 144}{ {b}^{2} = \sqrt{25} } \\ b = 5[/tex]

Therefore, x equals 5.

Answer:

x=5, y=-4

Step-by-step explanation:

:)

Answer:  If the original equation is y = 3x -4,  the slope is 3.

Any equation of a line parallel to the line y = 3x -4 will have a slope of 3.

Step-by-step explanation:

In slope-intercept form, y =mx + b the coefficient of x, m is the slope.

Here 3 is that value.

It is very unusual to have two equal signs in a question about slope.

I am not sure what to do with the =8y + 1

Is this supposed to be another equation in the system, missing a term?

Answer:

X=1/2

Step-by-step explanation:

2(x-3)+3=6x-5

2x-6+3=6x-5

2x-3=6x-5

2x-6x-3=-5

-4x=-5+3= -2

-4x= -2

x= 1/2

Answer:

y=−8x+53

Step-by-step explanation:

I think... I'm not sure so I'm sorry if its wrong

Answer: Here is an explanation of how to get the answer.

Step-by-step explanation:

It tells you the slope is -8, so you know your equation will look like this:

y = -8x + b,

where b is the intercept. You also are given a point that is on the line, so that is an x and a y value that are a solution to the equation. You can plug those in and solve for b.

5 = -8(6) + b

53 = b

So, your equation is y = -8x + 53

Answer:

y=mx+b

Step-by-step explanation:

standard slope intercept form. just plug in slope and intercept

it takes 5 years  for the shoreline to erode 15 feet to a grass line

Two or more expressions with an Equal sign is called as Equation.

The erosion rate of a coastline is approximately 3 feet per year

if erosion continues at the current rate, how many years will it take for the shoreline to erode 15 feet to a grass line

Let us formulate the equation

Let x be the number of years for 15 feet.

3/1=15/x

Apply cross multiplication

3x=15

Divide both sides by 3

x=5

which is 5 years,

adding 24 ft means, it would take 13 yrs.

3 x 8 = 24

Hence it takes 5 years  for the shoreline to erode 15 feet to a grass line
