You need to divide the numbers.
One 8 is in the tens place while one is in the hundreds place or 10(80) compared to 100 (800).
The answer is B becasue if you have 20 less 5 its going to be 15
I assume there are some plus signs that aren't rendering for some reason, so that the plane should be
.
You're minimizing
subject to the constraint
. Note that
and
attain their extrema at the same values of
, so we'll be working with the squared distance to avoid working out some slightly more complicated partial derivatives later.
The Lagrangian is
Take your partial derivatives and set them equal to 0:
Adding the first three equations together yields
and plugging this into the first three equations, you find a critical point at
.
The squared distance is then
, which means the shortest distance must be
.

See explanations
Step-by-step explanation:
We have only one equation which is:
The number of equation is 1.
This means that, there are infinitely many solutions to the given equation.
To find a solution, we choose a value for x, substitute it into the equation and then solve for y.
For instance, when x=0, we have:
Therefore (0,2) is one of the solutions.
