Please post the question ..i'll solve for x
Thank you for letting me help :)
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
I hope this helps you
cotx =cosx/sinx
cotx=0,85/0,52
cotx=85/52
cotx=1,6
Answer:
A
Step-by-step explanation:
I added 6.5 to the equation, found the mean, and it was 3.5.
