Answer:
The scale factor is 3.
Step-by-step explanation:
(IF YOU ARE READING THIS THIS IS INCORRECT, REFER TO THE COMMENTS THANK YOU, THE ACTUAL SCALE FACTOR IS 1/3 OR 0.33)
RQ on the right side is 5 and XW on the left side is 15. 15/5 = 3
This also means UV is 15 since it is a rectangle.
We can apply that to all sides and see if it works now.
RS on the right side is 8, so that means XU and WV on the left side is 24 since it is a rectangle.
24/8 is 3.
The scale factor is 3.
Answer:
-5a(2a^3+a-1)
Step-by-step explanation:

Answer:
D. y = -1/3x
Step-by-step explanation:
The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...
k = y/x . . . . . divide the above equation by x
For the given point (x, y) = (-3, 1), the value of k can be seen to be ...
k = 1/-3 = -1/3
Then the equation for the line is ...
y = -1/3x . . . . matches D
