andrew-mc [135]3 years ago
8 0

Answer:

Infinitely many solutions.

Step-by-step explanation:

2x-y=16

8y=4(4x-32)

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

y=2x-16

8(2x-16)=16x-128

16x-128=16x-128

infinitely many solutions

Point m is the midpoint of ab¯¯¯¯¯ . am=2x+9, and ab=8x−50. what is the length of am¯¯¯¯¯¯ ?
iogann1982 [59]
Since m is the midpoint of ab, then the following relationship is fulfilled:
 am =  \frac{ab}{2}
 Therefore, substituting values we have:
 2x+9 = \frac{8x-50}{2}
 From here, we clear the value of x.
 We have then:
 2x+9 = 4x-25
 9+25 = 4x-2x
 34 = 2x
 x =  \frac{34}{2}
 x = 17
 Then, the value of am, is given by substituting x in the expression:
 am=2x+9
 Substituting we have:
 am=2(17)+9
 am=34+9
 am=43
 Answer:
 
the length of am is:
 
am=43

2.   Using the external angle of a triangle theorem.

6x - 17 = 3x - 11 + 2x + 11

6x - 5x = 17

x  = 17

So  m angle K =  2(17) + 11

= 45 degrees   answer

3.  The diagonals are both medians of the triangle so the 2 parts are in the ratio  2:1  so  3:x = 2:1   and   x = 1.5  answer

2:1
