Answer:

(f/g)(8) = -169

Step-by-step explanation:

Simply plug in <em>x </em>= 8 into our equation:

\frac{3-2(8)}{\frac{1}{8 + 5} }

\frac{-13}{\frac{1}{13} }

-13(13)

-169

#4. Find the value of x and use it to find the length of<br> CE, BD, and BE<br> Find BD.
almond37 [142]

Answer:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE

Step-by-step explanation:

<u>We know that:</u>

  • BD = 2x - 4
  • DE = 2x - 3 - 2
  • BE = 3x - 1
  • CE = 2x - 3

<u>Solution:</u>

  • (2x - 4) + (2x - 3 - 2) = 3x - 1
  • => 2x - 4 + 2x - 3 - 2 = 3x - 1
  • => 4x - 9 = 3x - 1
  • => 4x - 3x = 9 - 1
  • => x = 8
  • => 2x - 4 = BD
  • => 2(8) - 4 = BD
  • => 16 - 4 = BD
  • => 12 = BD
  • => 3x - 1 = BE
  • => 3(8) - 1 = BE
  • => 24 - 1 = BE
  • => 23 = BE
  • => 2x - 3 = CE
  • => 2(8) - 3 = CE
  • => 16 - 3 = CE
  • => 13 = CE

Hence, the answers are:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE
