proportional relationships have constant ratios.
the graph is a line, so it is a proportional relationship. (A)
the function is in the form y=kx (proportional function) (C)
Find the ratio of the tables: (B)
![m=\frac{-0.8-(-1.6)}{-2-(-4)}=0.4=\frac{0.4-(-0.8)}{1-(-2)}=\frac{1.2-0.4}{3-1}=](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-0.8-%28-1.6%29%7D%7B-2-%28-4%29%7D%3D0.4%3D%5Cfrac%7B0.4-%28-0.8%29%7D%7B1-%28-2%29%7D%3D%5Cfrac%7B1.2-0.4%7D%7B3-1%7D%3D)

All represent a proportional relationship
Answer:
The domain of exponential functions is all real numbers. The range is all real numbers greater than zero. The line y = 0 is a horizontal asymptote for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases.
Answer:
The student incorrectly simplified 10ab root 2a + 20a root 2a
Step-by-step explanation:
The answer is 1:11. After it being simplified from 6:66. Hope this helps.
Answer:
12 9/10 tons
Step-by-step explanation:
The answer would be 12 9/10 tons. The only thing you are doing is adding them together.
Correct me ANYONE if I'm wrong.
