Answer:

2\sqrt{34}

Step-by-step explanation:

We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.

6^2 + 10^2 = x^2\\x = \sqrt{6^2 + 10^2}\\ = \sqrt{136} \\= 2\sqrt34}

hope this helped! :)

Answer:

  XF·XG = 17

Step-by-step explanation:

Drawing a cyclic quadrilateral from side lengths is interesting enough. I have no idea how to compute the desired value, but my geometry program says it is 17.

In the attached, XF is line segment m, approximately 7.63 in length. XG is line segment n, approximately 2.23 in length. The product is the number "o", shown at the end of the red arrow.

2. x + y = 82
    x - y = 24
  ---------------add
    2x = 106
      x = 53
 
   x + y = 82
   53 + y = 82
   y = 82 - 53
   y = 29

   solution is : (53,29)
=======================
3. y = 2x
    y = 4x + 6
    
    2x = 4x + 6
    2x - 4x = 6
    -2x = 6
     x = -3

    y = 2x
    y = 2(-3)
    y = -6

    solution is (-3,-6)
========================
4. 5x + 8y = -29
    7x - 2y = -67...multiply by 4
   ----------------
    5x + 8y = -29
   28x - 8y = - 268 ..result of multiplying by 4
  -----------------add
   33x = - 297
      x = - 9

   5x + 8y = -29
   5(-9) + 8y = -29
    -45 + 8y = -29
   8y = -29 + 45
   8y = 16
   y = 2

   solution is : (-9,2)
=======================
5. y = -4x + 6
    y = -5x - 4

    -4x + 6 = -5x - 4
    -4x + 5x = -4 - 6
     x = -10

    y = -4x + 6
    y = -4(-10) + 6
    y = 40 + 6
    y = 46

   solution is (-10,46)
=========================
6. H(m) = 2m + 12
    H(m) = 3m + 10
=========================
7. -8x + 4y > -52
    4y > 8x - 52
     y > 2x - 13 <==
=========================
8. 3x - y = 28
    3x + y = 14
   ---------------add
    6x = 42
     x = 7

   3x - y = 28
   3(7) - y = 28
   21 - y = 28
   -y = 28 - 21
   -y = 7
    y = -7

solution is (7,-7)
=====================
10. 5x - 5y > 70
      -5y > -5x + 70
       y < x - 14 <==
=====================
11. sorry...dont know
=====================
12. y = 4x + 4
      y = -3x - 3

     4x + 4 = -3x - 3
     4x + 3x = -3 - 4
     7x = -7
     x = -1

     y = 4x + 4
     y = 4(-1) + 4
     y = 0

solution is (-1,0)
=======================
13. -12x - 2y > - 42
       -2y > 12x - 42
        y < -6x + 21 <==
=======================
14. -5x + 2y = 9
       3x + 5y = 7

solution is (-1,2)
========================
15. 3x + 6y = -2
     15x + 30y = -10....divide by 5 to reduce = 3x + 6y = -2
     is the same line....infinite solutions
========================
1. (the graph).....y < = 3x - 4....3rd one
========================
9. (2nd graph)....y < = -3x + 4....last one
