Answer:
Option B.
Step-by-step explanation:
Given:
-3( -x + a ) + 7 < 5 When x = -1
To Find:
a ?
Solution:
-3( -x + a ) + 7 < 5 When x = -1
Substitute x = -1 in above we get
-3(-(-1) + a ) + 7 < 5
-3(1 + a) < 5 - 7
Using Distributive Property we get i.e A(B+C) = AB + AC
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
