B -3/4 you take the two points
We're minimizing

subject to

. Using Lagrange multipliers, we have the Lagrangian

with partial derivatives

Set each partial derivative equal to 0:

Subtracting the second equation from the first, we find

Similarly, we can determine that

and

by taking any two of the first three equations. So if

determines a critical point, then

So the smallest value for the sum of squares is

when

.
Answer:
5:7
Step-by-step explanation:
A pet store has two types of betta fish which is red and blue
She noticed that 7 out of the 12 beta fishes are red
This means that there are 7 red beta fishes and 5 blue betta fishes
Therefore the ratio of blue betta fish to red betta fish is
= 5:7
x = -52 4/17
