Hello :
<span> -7x-6y=59...(1)
-8x-6y=58...(2)
(1)-(2) : x = 1
subsct in (1)
-7-6y = 59
6y =-66
y = -11

The equation of any circle is
(x - a)^2 + (y - b)^2 = radius^2 where our center is (a, b)
Therefore, our equation is as follows.
(x + 2)^2 + (y - 3)^2 = 16
The first one is C
Im not quite sure about the other ones
Answer:
Most Likely English because there are more english than the other lanaguages.
Step-by-step explanation:
For this case we have by definition, that the derivative of the position with respect to time is the velocity, that is to say:

So:
Taking into account that the derivative of a constant is 0.

So, the velocity is -14
Answer:
-14
