set the derivative to 0, solve for "x" to get any critical points
keep in mind, setting the denominator to 0, also gives us critical points, however, in this case, the denominator will never be 0, so... no critical points from there
there's only 1 critical point anyway, and do a first-derivative test on it, check a number before it and after it, to see what sign the derivative has, and thus, whether the graph is going up or down, to check for any extrema
Step-by-step explanation:
the answer is C.
I hope it will be help you.....
Answer:
A careful observation of many rude individuals will reveal that they are deeply insecure, with low self-confidence and a lack of understanding about human behavior. As the Brazilian novelist Paul Coelho sagely observed: “How people treat others is a direct reflection of how they feel about themselves.”
Step-by-step explanation:
plzzzzzzz Mark my answer in brainlist
and follow me
So, for the first variable, you would use x, and for the second, y. Then, you would write out 2-(3y)=14. once this is done, youd simplify to 2-3y=14. Subtract 2 from both sides to get 3y=12. Then, divide both sides by 3. this will leave you with y=4. From this you can see the other number is ten. Hope this helped! and i apologize if it is incorrect!
