Answer:
Point A, B, and C are collinear points.
Step-by-step explanation:
When points lie on one line, meaning all of the points are on the same line --> this is known as collinear points.
So assuming that the total =27
r+b=27
r=-5+3b
r=3b-5
subsitute 3b-5 for r in first equation
3b-5+b=27
4b-5=27
add 5
4b=32
divide by 4
b=8
subsitute
b+r=27
8+r=27
subtracct 8
r=19
red=19
blue=8
-15.18 is the answer and you have added a = sign by mistake
Answer:
The population growth is 6.26 per square mile per year
Step-by-step explanation:
We are given
he US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years
So,
Initial population =128.7
Final Population =191.3
Total time =10 years
now, we can find population grow per year
![=\frac{final-initial}{T}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bfinal-initial%7D%7BT%7D)
now, we can plug values
![=\frac{191.3-128.7}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B191.3-128.7%7D%7B10%7D)
![=6.26](https://tex.z-dn.net/?f=%3D6.26)
So,
The population growth is 6.26 per square mile per year
