by dy/dx, we'll be assuming that "y" is encapsulating a function, a function in terms of "x".

Step-by-step explanation:
1. 48 decide by 16 = 3 per min
2. Decide by 7 you will get 5:2
3. 24 per hour so 3 hours is 3 times 24 which is 72
4. 5cm per hour
5. 175:326.
6.1080 decide by 9 you get 120
120 times 13 is 15607.
7. 2520 decide by 9 is 280
Sara got 560 while Hina got 19608.

Step-by-step explanation:
Answer: Option A and Option D
Step-by-step explanation:
By definition the general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
All points that are on the x axis have the following form:
(h, 0)
Therefore all the circles that have their centers on the x axis will have a value of k = 0.
Identify among the options all those equations that have a value of k = 0
The circles that have their center on the x axis are option A and option D
