here's the solution,
let the length of shorter peice = x
then the lenght of longer peice = 6x + 8
now, we know that the sum of length of peices measures 99 feet,
So,
=》x + 6x + 8 = 99
=》7x = 91
=》x = 13
shorter piece length = 13 feet
longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
For
|a|>15
assume
a>15
a<-15
so
x+6>15
minus 6
x>9
x+6<-15
minu 6
x<-21
B is answer
Answer:

Step-by-step explanation:
We know that 
Also , 
So ,

Answer:
The graph shows a steady declining plot as the aveage traffic volume increases. Since y axis is speed the correct answer is that as traffic volume increases the average vehicle speed decreases.
Step-by-step explanation:
8x+6=62
8x=62-6
8x=56
X=56/8
X=7
The answer is 7. Hope this helps!
