Answer: The inverse is f^-1 (x) = x - 11
Answer:
-23x+1
Step-by-step explanation:
91-14x - (9x+90)
91-14x-9x-90
-23x+1
<span>Complementary angles sum up to 90 degrees and supplementary angles sum up to 180 (I remember that because they are alphabetical).
90 - 71.4 = 18.6
180 - 71.4 = 108.6
Therefore, D. is the answer.</span>
