Answer:
x = 20
Step-by-step explanation:
These 2 angles are supplementary so they add up to 180:
3x - 10 + 5x + 30 = 180
8x + 20 = 180
8x = 160
x = 20

I believe your answer is:
No, it is not a function.

Here’s why:
⸻⸻⸻⸻
- If we preform a vertical line test on the graph, then the line would pass the relation multiple times. This means that it is not a function.
- See the picture attached.

Hope this helps you. I apologize if it’s incorrect.
9(.80) = 7.2(.80) = 5.76(.80) = 4.608. round it and it is 4.6 feet
<span>The entire expression should be subtracted from 30. To subtract the quantity, distribute the negative sign, which changes the signs on the terms. So, the –2 changes to positive and gets added to 30 instead of subtracted from it.
Hope this helps! ^^</span>
