Given that AXB is complementary to both CYD and FZE, and mAXB = 36°, what is mCYD + mFZE?
anyanavicka [17]
Complementary angles always equal 90°
So here is how to find what mCYD + mFZE equal 
mCYD + mFZE + mAXB
mCYD + mFZE + 36° = 90°
Subtract 
mCYD + mFZE = 54°

Which representation does NOT represent y as a function of x?
siniylev [52]
<h3>Answer: Choice C</h3>

Why isn't choice C a function? It's because we have the input x = 4 lead to more than one output at the same time (y = 5 and y = -5). A function must have all allowed inputs lead to exactly one output.

The diagram for choice C shows we have the points (4,5) and (4,-5). If we plotted those two points, then a vertical line forms, which will show this relation fails the vertical line test.

Choices A, B, and D do not have this happen where a certain input leads to multiple outputs at once; therefore, these are all functions. For the tables A and D, note there aren't any repeated x values. If you were to convert choice C into table form, then you would have the x value 4 repeat itself.

PLZ HELP! WILL GIVE BRAINLIEST TEN POINTS
Tatiana [17]

Answer:

Time = distance/speed. T = 1,200,000,000/28,000. This can be cancelled to 1,200,000/28. Rounding 28 to 30 for the estimate, divide by another ten: 120,000. Then divide by the remaining 3 from 30: 120,000/3 = 40,000. It will take approximately 40,000 hours.

<em>Hope This Helps!</em>
