Answer:
Option B. No, because the graph of the line connecting the ordered pairs does no pass through the origin.
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
In a proportional relationship the constant of proportionality k is equal to the slope m of the line<u><em> and the line passes through the origin</em></u>
step 1
Connect the ordered pairs of the graph
The y-intercept is the point (0,20)
see the attached figure
That means, that the line not passes through the origin
therefore
The relationship between the two quantities is not proportional

Answer:
The slope is -5/7
Step-by-step explanation:
Slope is rise / run. In other words, the change in y / change in x:
Answer:
The common ratio of the first G.P. series will be the cube root of the common ratio of the second G.P. series.
Step-by-step explanation:
Let us assume that the first series has first term a and the common ratio r and is given by
a, ar, ar², ar³, ......... up to infinite terms
It is given that the terms of the second series are a cube of the corresponding terms of the first series.
So, the second series is up to infinite terms.
So, it is clear that the second series is a G.P. series with first term a³ and common ratio r³.
Therefore, the common ratio of the first G.P. series will be the cube root of the common ratio of the second G.P. series. (Answer)
