5 is your missing factor because 9*5=45 btw dont use x for multiplication use this *
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:
y = -x +6
Step-by-step explanation:
The 2-point form of the equation for a line through points (x1, y1) and (x2, y2) is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For your given points, this is ...
y = (1-4)/(5-2)(x -2) +4 . . . . with given points filled in
y = -1(x -2) +4 . . . . . . . . . . . simplify a bit
y = -x + 6 . . . . . . . . . . . . . . simplify to slope-intercept form
I remember this but I dead forgot how to do it
