ANSWER



x=10


and


y=20




EXPLANATION



Since corresponding angles are equal,


4x+y=60---(1)




Alternate angles are also equal, therefore,


8x+y=100---(2)



Equation (2) minus equation (1) gives,



\Rightarrow 4x=40




\Rightarrow x=10




We put x=10 in to equation (1)





4(10)+y=60



y=60-40




y=20

Which function represents a reflection of f(x)=3/8
Leni [432]

Answer:

Step-by-step explanation:

Reflecting a function across the Y axis means replacing x with -x.

First one could *almost* work, if there wasn't the minus sign at the beginning, so it's a no.

Second one is also a no, the original one is always positive, the second one is always negative.

3rd one is reflecting the graph all right, but it's also adding some sort of stretch (try with the point x=1 in both cases, f(1) = \frac 32 while g_3(1) = 2/3

4th one is the charm.
