Answer:A vertex (or node) of a graph is one of the objects that are connected together. The connections between the vertices are called edges or links. A graph with 10 vertices (or nodes) and 11 edges (links).
Step-by-step explanation: (The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
4" x 2500 ft², namely 4 ft x 2500 ft², will just be 4*2500*ft*ft², or 10000 ft³.

since there are 27 ft³ in 1 yd³, then how many yd³ are there in 10000 ft³?
10000/27, that many yd³.
subtract them
593.7-573.36 = 20.34seconds
so c is the answer
"evaluate 10(4+3*2)/(2*6-7)
Y=2×2
y=4
4=-3x-1
now add 3x on both sides
3x+4= -1
now substract 4 on both sides
3x = -5
divide 3 on both side
x=-5/3
y= 4
x= -5/3
