Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
Answer:
y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.
I believe the equation to be . If you meant , please let me know.
Thanks kindly.
Step-by-step explanation:
If (-1,y) lies on the graph of , then by substitution we have:
.
We just need to simplify to determine y:
Multiply the 2 and -1:
Use reciprocal rule for exponents to get rid of the negative:
just means :
.
