Answer: Choice A) y = cx
The 'c' is the constant of variation
For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.
Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.
Answer:
3/5

I would say the 12 pack for $7
Answer:
smaller: 30°
larger: 150°
Explanation:
1) Given: sinθ = 1/2
2) That is a notable value.
You know that sine ratio is 1/2 for angles 30° and 180 - 30° = 150°
3) Therefore the angles are: smaller= 30°, larger = 150°
