Answer:
the third option cannot be a function
Step-by-step explanation:
whenever a set or ordered pairs contains an x-value that appears more than once then it cannot form a function
The rationalized form of 1+ √2/1-√2 is -2√2-3
Answer:
Step-by-step explanation:
x + 32 + 2 vertically opposite degrees = 180 Beginning condition
x + 32 + x + 126 + 36 = 180 Combine like terms
2x + 194 = 180 Subtract 162 from both sides
2x = -14
x = -7
========
So the three angles are
36
-7 + 32 = 25
-7 + 126 = 119
Total = 180
That negative can throw you for a loop.
