Can you help me solve
Sloan [31]
The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
  GX/BX = UH/NH
  GX = BX·UH/NH
  GX = 7·18/(3√11)
  GX = (42/11)√11

  GB/BX = UN/NH
  GB = BX·UN/NH
  GB = 7·15/(3√11)
  GB = (35/11)√11

PLEASE HELP IM BEGGING! U WILL EARN 85 POINTS - WILL MARK BRAINLIEST
dimulka [17.4K]

Answer:

See below

Step-by-step explanation:

<h3>Part A</h3>
  • The graph is attached
<h3>Part B</h3>
  • |2x - 4| = mx + 1

It has only one solution when the line mx + 1 is parallel to one part of |2x - 4|.

As per graph, we see m = 2 makes it parallel to y = 2x - 4. This is the only solution.

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

Now, as I understand, you are looking for 2 solutions instead of one. It means the line mx + 1 will have 2 points of intersection with the line |2x - 4|.

One of those solutions is attached as well, where m = 1. And you may get many more options for this.

What is the reciprocal of -1/4
Rzqust [24]

Answer:

-4/1 or -4

Step-by-step explanation:

A reciprocal is found by switching the numerator and denominator. So if we ignored the negative sign and found the reciprocal of 1/4, it is 4/1. Now, if you add the negative sign, you get -4/1. If you simplify, you get -4. I'm not really too sure on my answer so you can ask more than one person. I hope you get the help you need!
