(3x + 13) + (8x + 14) + 109 = 180°
(3x + 13) + (8x + 14) = 71°
11x + 27 = 71°
11x = 44°
x = 4
Is there a photo with this
Answer:
A and B only
Step-by-step explanation:
The table has x=10 that maps on to y=5 and y=-5.
This disqualifies the table for being a function.
The ordered pairs has no x-value repeating.
The graph of y=x² +10 is a vertical parabola that passes the vertical line test, hence it is also a function.
For a relation to be a function, no x-value must repeat; this means its graph must pass the vertical line test
