Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)

b) which is attained at
Step-by-step explanation:
<u>Step(i)</u>:-
Given function
...(i)
Differentiating equation (i) with respective to 'x'
...(ii)

Equating Zero






<u><em>Step(ii):</em></u>-
Again Differentiating equation (ii) with respective to 'x'
put


The absolute minimum value at 
<u><em>Step(iii):</em></u>-
The value of absolute minimum value


on calculation we get
The value of absolute minimum value = - 0.3536
<u><em>Final answer</em></u>:-
a) The value of absolute minimum value = - 0.3536
b) which is attained at
Step-by-step explanation:
(4x-23)2-3=2
(4x-23)(-1)=2
4x-23= -2
4x= -2+23
=21
x=21/4
=5.2
