Answer:
Step-by-step explanation:
Subtract 3 from the right and do the same to the left which leaves you to x = -1
Answer:
80
Step-by-step explanation:
From the given diagram;
KN = NM
9x - 5 = 7x + 7
9x - 7x = 7 + 5
2x = 12
x = 12/2
x = 6
Since KM= 2KL
KM = 2(6x+4)
KM = 12x + 8
KM = 12(6)+8
KM = 72+8
KM = 80
Hence the length of KM is 80
A feature of every linear function is that the slope is the same no matter where you are on the line. When given a table of data that you suspect might represent a linear function the slope manifests itself as a constant common difference between successive y -values.
