Luckily, finding midpoints is very easy...
It is just the average of the coordinates...
((x2+x1)/2, (y2+y1)/2)
So for example: your first segment...
((2+8)/2, (3+5)/2) then the midpoint is: (5, 4)
Umm i would not trust that file
Answer:
C.) X=3 and X=-6/7
Step-by-step explanation:
Use the quadratic formula to solve
Answer:
1) 16x -4
2) 7x + 45
Step-by-step explanation:
1 ) 6x + 2(5x -2)
we are going to open the bracket
we have,
6x + 10x - 4
16x -4
4(4x - 1).................................................... simplified
number 2
7x + 3(8+7)
7x +24 + 21
7x + 45........................................................... simplified
so therefore the solution to the first and 2nd question is
1) 16x -4
2) 7x + 45
