Answer:
Step-by-step explanation:
14x - y = -1
14x = y -1
14x +1 = y
Substitute into other problem:
3x + 2(14x +1) =13
3x + (28x + 2) = 13
31x + 2 = 13
31x = 11
x = 11/31
Answers:
- Reason 2) Given. Specifically, the diagram shows that the two angles are adjacent and supplementary, which is why the two angles are a linear pair.
- Reason 3) Definition of Linear Pair. As stated above, a linear pair of angles add to 180 degrees (they are supplementary).
- Statement 4)
since the term "right angle" is another way of saying "90 degree angle" - Statement 5)
The upside down "T" symbol means "perpendicular". Perpendicular lines form 90 degree angles at the intersection.
Side note: The double arrow over WY and XV in statement 5 is supposed to be an unbroken line.
