9 - 8x = 35
subtract 9 from both sides
-8x = 26
divide both sides by -8
x= -26/8
you can simplify this to -13/4
I'm sorry, I don't see the question. Could you please retake the photo in better quality so I could answer it? Thanks!
Yea it’s B because I did the mathhhhhh
Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]
