Answer:
( -2 , 0 ) maximum
Step-by-step explanation:
Watch the graph and point out the coordinates.
if its vertex is less that 0 or negative, then maximum.
With vertex being greater than 0 or positive, its minimum.
Answer:
ok i have this same question so what you are going to take the 3 and just maove it to the side and then you fail
Step-by-step explanation:
Answer:
a) If a=20 the system has no solutions.
b) If a≠20 the system has exactly one solution.
Step-by-step explanation:
The augmented matrix of the system is .
Using rows operations we obtain the echelon form of the matrix, ie,
Since the echelon form of the matrix does not have free variables then the problem has exactly one solution or has no solutions.
a) If a=20 the system has no solutions because in the last equation solving for x3 it has that 0=24. Then the system is inconsistent.
b) If a≠20, the the system has exactly one solution that is obtained solving the system of the echelon form matrix.
Hey there!
The equation for axis of symmetry is
The A, B, and C are:
Ax+By+C= f(x)
A=4 B=-8 C=12
So we have:
Two negatives make a positive.
8/8= 1
x=1 is the correct answer.
I hope this helps!
