Answer:

Step-by-step explanation:
For shifted down a function you have to follow the next structured:

In our case is:

Now for compressed or shrink a graph you have to multiply by a factor in the input something like this:

In our case is:

Maybe you can think, why 5 and not
instead?. Well, when you multiply by
this dilate or stretch the graft because the output of each value is smaller, example:

Then evaluate for a number, for example 5:

the output of
is 5 steps a far from the answer of
this in a graph is illustrate as a stretching.
So the opposite happen when you multiply by a integer number, the graph is compressed because the output take the "faster steps".
So combine the two transformation and get 
Answer:
4a is s(50-30-20)
4b is 10

The answer is E I did a test like this before and they try to trick you
2x+8 = 8(x-5)
expand the rhs to get
2x+8 = 8x-40
now we minus 2x and add 40 to make one side without the unknown and the other with the unknown. you have
48 = 6x
x = 48/6
= 8
Answer:
True
Explanation:
Each of the outputs got their own input but the inputs share a output
