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
Answer:
The ordered pair is not a solution.
Use the slope formula, do the same for each question.
Slope= y2-y1/x2-x1
Question 4: (-1,-2) and (1,0)
-1 is x1, -2 is y1
1 is x2, 0 is y2
0- -2=2 (0 subtract -2, two minus signs equal to an addition sign.)
1- -1=2
2/2= 1
The slope is 1.
The answer is a positive 0.33
