Need help on this question
1 answer:
This is actually quite simple. You just have to remember that a triangles angle measures must equal up to 180. Also, you need to recognize which angles are supplementary angles (angles whose measure must add up to 180) That being said, 126 and A are supplementary angles. So are C and 41, and E and 38. To find out A, simply subtract 126 from 180 to get 54. Then, to get C, subtract 41 from 180 to get 139. Since you know A and C, you can figure out B, which is 85. Then, to find E, subtract 138 from 180. That equals 42. Now, simply add up 41 and 42, and shbtract it from 180. That gives you 97, which is D. I hope this helps! :)

Part 1: or
Part 2:
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get (since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:
Then in this case you turn y=f(x), but the system did it for you, so all you have to put is .
For the second part you must replace x with 2 since you need to find f(2).
Your answer for part 2 is .
