Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
Find the value of the constant of proportionality r
![r=y/x](https://tex.z-dn.net/?f=r%3Dy%2Fx)
For x=5.8, y=5.8
substitute
![r=5.8/5.8](https://tex.z-dn.net/?f=r%3D5.8%2F5.8)
![r=1](https://tex.z-dn.net/?f=r%3D1)
The linear equation is
![y=x](https://tex.z-dn.net/?f=y%3Dx)
therefore
The value of the constant of proportionality r is 1
I believe the answer would be 70 but make sure just in case.
Do they give you a graph?
No she is not right.
Dividing blocks by minutes would be 12/36 = 1/3
The ratio would be 1:3 meaning she runs 1 block every 3 minutes.
Answer:
it would be -19.9 bar notation over the 9
