A line is 180 degrees
(9n+2) + 90 + 34 = 180
(9n+2) + 124 = 180
9n+2 = 56
9n = 54
n = 6

Please help me!!!!!!!!!!!!!!!
ycow [4]

Answer:

  7)  (f+g)(x) = 4^x +5x -5

  8)  (f-g)(x) = 4^x +x +5

Step-by-step explanation:

7) add the two expressions.

  (f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)

  (f+g)(x) = 4^x +5x -5

__

8) subtract g(x) from f(x).

  (f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5

  (f-g)(x) = 4^x +x +5

Which statement is true when all points of a line lie in a plane?
stira [4]
Your answer would be choice 3, because when all points of a line lie in a plane, the plain contains the line so the line can contain all of the points. Hope this helped. ;)
