The value of x in the figure is 9.72

<h3>How to determine the value of x?</h3>

The given shape is a triangle, and the value of x can be calculated using the following laws of cosine

a^2 = b^2 + c^2 - 2bc * cos(a)

So, the equation becomes

x^2 = 14^2 + 10^2 - 2 * 14 * 10 * cos(44)

Evaluate the value of cos(44)

x^2 = 14^2 + 10^2 - 2 * 14 * 10 * 0.7193

Evaluate the product

x^2 = 296 - 201.404

Evaluate the difference

x^2 = 94.596

Evaluate the exponent

x = 9.72

Hence, the value of x in the figure is 9.72

Solve the system of equations:<br> y = x-4<br> -2x + y = 18

Pie

Answer:

x = 7.3

Step-by-step explanation:

-2x + x-4 = 18

First, Combine Like Terms

-3x + (-4) = 18

Then, do Inverse Operations

-3x + -4 = 18

+ 4 +4

Cancel out the -4 +4 because it will equal zero and won't matter to the equation

-3x = 22

Do Inverse Operations again. In this case, you will divide.

-3x = 22

-3x/-3 = 22/-3

Cancel out the -3x/-3

22/-3 = x

7.3 = x

Find the value of x. Round to the nearest tenth.

vfiekz [6]

Answer:

Step-by-step explanation:

to find w:

sin(44) = w/30

w = 30sin(44)

w = 20.8 to 1 decimal place

to find x;

cos(x) = 20.8/45

x = $cos^{-1}$ (20.8/45)

x = 62.46940334

x = 60

Find the solution set of the following equations: <br><br>2y=2x+7<br><br>X=y+2

kirill115 [55]

Answer:

The system of equations has no solution.

Step-by-step explanation:

Given the system of equations

2y = 2x+7

x = y+2

solving the system of equations

$\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}$

Multiply -y+x=2 by 2: -2y+2x=4

$\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}$

so adding

$-2y+2x=4$

$+$

$\underline{2y-2x=7}$

$0=11$

so the system of equations becomes

$\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}$

0 = 11 is false, therefore the system of equations has no solution.

Thus,

No Solution!
