Will mark best answer.. The equations in this sytem were added to solve for x. What is the value of x? -2x+y=8 5x-y=-5 3x=3
Juli2301 [7.4K]

The value of x=1

Step-by-step explanation:

Given the equations as :

-2x + y= 8

 5x  - y= -5  ------adding the equations

---------------------

  3x     =   3  -------dividing both sides by 3

  x       =    1

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg ha
anastassius [24]
Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α 

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.  

a² (24) + β² ( x ) = c² (74) 

Calculations 

c² = α² + β²

74² = 24²+ β² 

<span>5476 = 576 + </span>β² 

5476 - 576 = β²
<span> </span>
<span>4900 = </span>β² 

→√4900 
<span> </span>
β<span> = 70 yards 
</span>
<span>70 = 10x 
</span>
<span>x = 70</span>÷<span>10 = 7 yards  
</span>
The second leg = 7 yards

in the system shown below, what are the coordinates of the solution that lies in quadrant I? x^2-y^2=25, x+y=25
vodomira [7]
The given equations in this item are,
                     x² - y² =25
and 
                    x + y = 25

It can be deduced that the first equation is a difference of two squares and can be factored out as that one shown below.
           (x - y)(x + y) = 25

From the second equation, x+y = 25. Substituting this to the equation above,
             (x-y)(25) = 25
Hence, x - y = 1

The system of linear equations is,
                  x + y = 25
                  x - y = 1
Adding the equations together,
         2x = 26
        x = 13

The value of y is 12.

Since both x and y are positive values then, this solution lies in the first quadrant.
