Answer:
x = 2
Step-by-step explanation:
-3x - 6 = 8x + 16
8x - 3x = 16 - 6 (subtract like terms)
5x = 10 (divide by 5)
x = 2
Vertical angles are equal and supplementary angles add to 180 degrees
6x + 2y = 18
2y = -6x + 18
y = -3x + 9
The proportional relationship should require they y-intercept and is then 0 and the linear relationship should be in a straight line to be a linear! Hope this helps!
Answer:
418 4/10
Step-by-step explanation:
To answer this we subtract 450 7/10 from 869 1/10.
We must borrow a '1' from 869 1/10: 868 11/10
Now subtract 450 7/10 from 868 11/10:
418 4/10 (CHANGE IN ELEVATION)
This reduces to 418 2/5.
