Easy peasy
the midpoint between
and 
is
just average them
so given that (3,5) is the midpoint of (-4,5) and (x,y)
so by logic
and 
times both sides by 2 for everybody
-4+x=6 and 5+y=10
add 4 to both sides for left one and minus 5 from both sides for right
x=10 and y=5
the coordinate of point C is (10,5)
the x coordinate is 10

Answer:
- The circles radious increases
- The circles moves left
- The circles moves down
Step-by-step explanation:
- The equation of a circle can be written as
, where "r" is the radious, and (a,b) are the coordenates in the axis x and b respectively.
- Then, in the first circle the coordenates are (0,7), which means that the circle will be center there, and the radious is 7 (
).
- The second circle have different coordenates: (-5,4), which means that the circle has moved left (from 0 to -7 in the x axis) and down (from 7 to 4 in the y axis). Additionally, its radious has increased from 7 (
).
- See the attached figure please.
- Then, the <u>correct answers</u> are:
- The circles radious increases (from r=7 to r=8)
- The circles moves left (from x=0 to x=-5)
- The circles moves down (from y=7 to y=4)
