Answer:
B. RY/RS=RX/RT=XY/TS
Step-by-step explanation:
In the picture attached, △RST and △RYX (which are similar) are shown
The options are:
Given that the triangles are similar, then their sides are proportional. Then, there is some constant k, which satisfies:
k*RS = RY
k*RT = RX
k*TS = XY
This can be rewritten as:
k = RY/RS = RX/RT = XY/TS
B.
There are no black pieces of paper in her closet so it’s impossible to get black
With Function Notation, f(x) just means the y. Since the equation is y = 50 - 1.99x you just replace y with f(x). If they ask you to solve the equation you created just plug in the number of songs into x. Example: x=5 so f(5)
