Answer:

Step-by-step explanation:
Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.
To find the distance between P and Q given their coordinates, use the distance formula:

Let:

The distance between these points is equal to:

Answer: C) f(-4) = 54
GIVE ME A THANKS
Step-by-step explanation:
f(x) = 7 ( 3 - x ) + 5
f(-4) = 7 ( 3 - (-4)) +5
f(-4) = 7 ( 7 ) + 5
f (-4) = 49 + 5
f (-4) = 54
