Find NQ if NP = 13 cm and line l is a segment bisector.
Zielflug [23.3K]

Answer:

NQ = 26 cm

Step-by-step explanation:

A line bisector divides a line into two equal segments.

Given that line l is the bisector of segment NQ, it then means it divides NQ into two equal segments, namely, segment NP and segment PQ.

Thus, NP = ½ of segment NQ

Therefore, if NP = 13 cm,

13 = ½*NQ

multiply both sides by 2

2*13 = NQ

26 = NQ

NQ = 26 cm

F(x) = 3 - 2x and g(x) =<br> 1/X+5 what is the value of<br> (f/g)(8)
Nina [5.8K]

9514 1404 393

Answer:

  (f/g)(8) = -104/41

Step-by-step explanation:

Fill in the value for x and do the arithmetic.

  f(8) = 3 -2·8 = 3 -16 = -13

  g(8) = 1/8 +5 = (1+40)/8 = 41/8

Then the ratio is ...

  (f/g)(8) = f(8)/g(8) = -13/(41/8) = -13(8)/41

  (f/g)(8) = -104/41

The image of the polygon ABCDE reflected across the x-axis. A(-1,-1),B(0,1),C(4,2),D(6,0),E(3,-3) The vertices of the image are.
4vir4ik [10]

A reflection across the x-axis has the rule:

(x,y)→(x,-y).

Then:

  • A(-1,-1)→A'(-1,1),
  • B(0,1)→B'(0,-1),
  • C(4,2)→C'(4,-2),
  • D(6,0)→D'(6,0),
  • E(3,-3)→E'(3,3).

Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
