You might want to check my work. I’m not sure if this is correct.
9p^2+8p+10
25p^2+6p+6
The governing equation is z = k/x.
When x=3, z = 1 2/3, or z = 5/3. Find k: 5/3 = k/3. Then k = 5, and the
governing equation becomes z = 5/x.
Now if x=12,
z = 5/12 (answer)
7-8x+12 = -8x+19
Your answer is D.
50 honestly have no clue sorry
