Answer:
Non-Proportional
Step-by-step explanation:
It goes through (0,0) ; (1,1) ; so it should go through (2,2) ; but it goes through (4,2). Therefore it is not proportional.
Answer:
200:1
Step-by-step explanation:
- simplify each by six
- 1200 by 6, you get 200 and 6 by 6 is 1
Answer:

Step-by-step explanation:
Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.
To find it, we use the given point of g, (2,1)
So g(2) = 1
meaning that
a·2² = 1
4a = 1
a = 1/4
Answer:
133°
Step-by-step explanation:
angles on a straight line = 180°
180 - 144 = 36°
angles in a triangle = 180°
36 + 31 = 67
180 - 67 = 113
answer = 113°
