Step-by-step explanation:
so what you're going to want to do is set this equal to 0. add the 6 over. add the 30 over. subtract 16x-14x they have the same degree of power so you can do that. divide the coefficient of x over and x=12 maybe who really knows anymore
A is the answer hope it helps you
Answer: c. 29.65 + 0.90r ≤ 41
Answer:
-1/2
Step-by-step explanation:
When the equation of a line is given in the form y = mx + b like this is, the slope is simply the m value!
so that
For a function , we have by the chain rule,
and
Let and . This substitution is made just to make the application of the chain rule clearer.
Differentiating again wrt gives
By the chain rule,
and our substitution shows that, for instance,
and so
Similarly, we find
Putting everything together, we have
and we can similarly find that
Adding together these derivatives, we see the mixed partials cancel, and recalling that , we end up with
as required.
