U would equal 206/86 or 2.39585
My answer is B and A that's my answer
Answer: Yes -40 is the answer
Explanation:
-12 = u/8 - 7
8(-12)/8 = u/8 - 8(7)/8
-96/8 = u/8 - 56/8
-96 = u - 56
-u = -56 + 96
-u = 40
u = -40
For this case we have the following function:

We apply the following function transformation:
Horizontal translations:
Suppose that h> 0
To graph y = f (x + h), move the graph of h units to the left.
We have then for h = 1:

Rewriting we have:

Rewriting we have:

Answer:
The resulting function when f (x) is shifted to the left 1 unit is:

It looks like angle FPG = twice angle FHG - which makes sense looking at it now, but I came up with the answer another way - see attached
