Answer:
Step-by-step explanation:
If a system of equations has infinite solutions, the graphs represented by the equations are exactly the same.
Answer:
x=-2.5
Step-by-step explanation:
has critical points wherever the partial derivatives vanish:
Then
- If
, then 
; critical point at (0, 0) - If
, then 
; critical point at (1, 1) - If
, then 
; critical point at (-1, -1)
has Hessian matrix
with determinant
- At (0, 0), the Hessian determinant is -16, which indicates a saddle point.
- At (1, 1), the determinant is 128, and
, which indicates a local minimum. - At (-1, -1), the determinant is again 128, and
, which indicates another local minimum.
The correct answer is C. if you plug zero in for 'x' you will get the y-intercept.
-2(0-2)(0-4)= -2(-2)(-4)=-16
Next set each factor equal to zero to get the x-intercepts.
(x-2)=0 x = 2 (2,0)
(x-4) = 0 x = 4 (4,0)
I hope this helps
Answer:
63
Step-by-step explanation:
Just input 3 instead of x, you would get 14(3) + 21 = 63
