Answer:
D.
Step-by-step explanation:
The point must be a critical point but it could be a saddle point. If the point is a saddle point it would not be neither a maximum nor a minimum. So it must be critical but it does not follow directly that it has a local maximum or local minimum.
Therefore D. (a,b) would be a candidate, but is not necessarily a maximum or minimum. It could be a saddle.
x^2 = 7x - 10
x^2 - 7x + 10 = 0
(x - 5)(x - 2) = 0
x = 5 or x = 2
The answer is B.
Answer:
y=3x
Step-by-step explanation:
Answer:
The scale factor is
Is a reduction
Step-by-step explanation:
we know that
The scale factor is the ratio of the corresponding side of resulting triangle by the corresponding side of the first triangle
Let
z-----> the scale factor
x------> the corresponding side of resulting triangle
y------> the corresponding side of the first triangle
so
In this problem we have
substitute
The scale factor is less than one
therefore
Is a reduction
