Answer:
A, B, D and F.
Step-by-step explanation:
Rin spends $20 every week on drum lessons.
If:
d = total amount of dollars Rin spends
w = number of weeks
Then: d=20w
w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:
(A)The independent variable causes a change in the dependent variable.
(B)The equation is d = 20w.
From the equation: d=20w
When w=1, d=$20
When w=2, d=$40
When w=3, d=$60
When w=4, d=$80
This tallys with the values in Option F.
Therefore:
(D)As the number of weeks increases, the total dollars Rin spends increases.
The correct options are: A, B, D and F.

Answer:
The total number of solutions is one
Step-by-step explanation:
we have


To solve the system of equations equate f(x) and g(x)

The solution of the system of equations is the intersection points both graphs
Using a graphing tool
see the attached figure
The solution of x

There is only one point of intersection both graphs
therefore
The total number of solutions is one
