Answer:
![x=\boxed{20}](https://tex.z-dn.net/?f=x%3D%5Cboxed%7B20%7D)
Step-by-step explanation:
The vertical angles have the same measure, so ...
3x +50 = 6x -10
60 = 3x . . . . . add 10-3x
20 = x . . . . . . divide by 3
Answer:
degree 3
Step-by-step explanation:
Note that
(- 3)³ + 4 = - 27 + 4 = - 23
(- 2)³ + 4 = - 8 + 4 = - 4
0³ + 4 = 0 + 4 = 4
1³ + 4 = 1 + 4 = 5
2³ + 4 = 8 + 4 = 12
3³ + 4 = 27 + 4 = 31
Then
f(x) = x³ + 4 ← a polynomial of degree 3
