8x = 44 -4
8x = 40
x = 40/8
x = 5
0.50x-6=4
move -6 to the other side
sign changes from -6 to 6
0.50x-6+6= 4+6
0.50x= 10
divide by 0.50 for both sides
0.50/0.50x= 10/0.50
x= 20
Answer: x= 20
{(2, 3), (1, 5), (2, 7)} - NOT because 2->3 and 2->7
{(11, 9), (11, 5), (9, 3)} - NOT because 11->9 and 11->5
{(3, 8), (0, 8), (3, -2)}
- NOT because 3->8 and 3->-2
{(-1, 5), (-2, 6), (-3, 7)} - YES
Answer:
is congruent because are parralel
