10 + -70
Step-by-step explanation:
Answer:
57.4
Step-by-step explanation:
The answer is 13
Euler's formula:
F + V - E = 2
F - number of faces
V - number of vertices
E - number of edges
We have:
F = 7
V = ?
E = 18
7 + V - 18 = 2
7 + V = 2 + 18
7 + V = 20
V = 20 - 7
V = 13
For instance y=5x+1
ax=5 is your slope +b=1 which is your y-intercept
