Answer:
B. A and D
Step-by-step explanation:
In each of the tables, the x-values differ by 1. So, a linear relation will have the y-values differ by a constant amount. We observe the differences to be ...
A: 3, 3, 3 . . . . a constant, so this function is linear
B: 1, 3, 5 . . . . not a constant; non-linear
C: 1, -6, 13 . . . not a constant; non-linear
D; 0, 0, 0 . . . a constant, so this function is linear
Tables A and D represent linear functions.
Answer:
Step-by-step explanation:
You cannot find the exterior angles of any irregular nonagon. If it is a regular one, then you can. A regular nonagon has 9 sides and so 9 exterior angles all of which are equal to 360/9 = 40 degrees. The interior angle = 180 - 40 = 140 degrees.
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)
m = 
= 
= - 1
