Answer:
Option (B)
Step-by-step explanation:
Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,
P ∝ C
P = kC
k =
Here k = proportionality constant
Since, the given line passes through a point (3, 2),

Answer:
10
Step-by-step explanation:
F + V − E = 2
Where F is the number of faces, V is the number of vertices and E is the number of edges
F + 16 - 24 = 2
Combine terms
F -8 = 2
Add 8 to each side
F -8+8 =2+8
F = 10
