x=7
Step-by-step explanation:
Alternate interior angles so they are congruent. So, 13x+5=12x+12. Subtract 12x and get x+5=12. Subtract 5 and you get x=7
Axis of Symmetry:
x= -1/6
Answer:
A: -7 and 3
B: 1 and 9
C: -8 and 6
D: 4 and 10
Step-by-step explanation:
you just count the distance as your going:
-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
......^.........................................^
-7 and 3 are both 5 away from -2
