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.
Answer:
Yes
Step-by-step explanation:
Plug in the coordinate (5,9) into the equation
9=3(5)-6
9=15-6
9=9
Answer:
The correct answers are
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
Step-by-step explanation:
Given:
Distance represented by Y axis in kilometer.
Time represented by X axis in hour,
The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).
In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.
Therefore, the given below two options are correct
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
<u> All real numbers</u> is the answer
Answer:
-45j - 9k
Step-by-step explanation:
Multiply -9 and 5j first to get -45j
Multiply -9 and k to get -9k
