Answer:
The answer should be y ≤ 1/3x - 1 I believe
3x + 1y = ¹/₃ ⇒ 9x + 3y = 1
2x - 3y = 2²/₃ ⇒ 2x - 3y = 2²/₃
11x = 3²/₃
11 11
x = ¹/₃
3x + y = ¹/₃
3(¹/₃) + y = ¹/₃
1 + y = ¹/₃
- 1 - 1
y = ⁻²/₃
(x, y) = (¹/₃, ⁻²/₃)
A bar graph would be a better choice because it is able to show how often he/she has gotten a good score.
Answer:
0.5km/h
Step-by-step explanation:
Assume lake has no current.
.
V=distance / time
V=39km / 3h
V=13km/h
In water Assume boat used same power travelling
V=35km / 2h
V= 12.5km/h
Current is the difference 0.5km/h
