We know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
V - E + F = 2
clear F
F=2-V+E
in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8
the answer is8 faces
Answer:
x ≤ 4
Step-by-step explanation:
Given
x + ≤ 4 , that is
x + 2 ≤ 4 ( subtract 2 from both sides )
x ≤ 2 ( multiply both sides by 2 to clear the fraction
x ≤ 4
X=-.25,-.5,-1,1,.5,.25
y=1,2,4,-4,-2,-1
