Answer: a = -5
Step-by-step explanation:
First, open up the brackets, and solve it
-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)
bring the -8a to the left side, so that all the a’s are together
-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)
-12a + 8a = -22 + 42
solve
-4a = 20
divide -4 on both sides
a = -5
Answer:
a ∥ b
Step-by-step explanation:
The symbol "∥" means parallel lines.
Taking a look at the figure above, we have 2 parallel lines, labelled a and b.
A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".
Same applies to line "b", which has 2 points forming segment CD.
Therefore, the correct label if the parallel lines is a ∥ b
