Suppose that g = (v, e) is a directed graph. a vertex w ∈ v is reachable from a vertex v ∈ v if there is a directed path from v to w. the vertices v and w are mutually reachable if there are both a directed path from v to w and a directed path from w to v in g.

show that { (u, v) | u and v are mutually reachable in directed graph g = (v, e) } is an equivalence relation (i. e., reflexive, symmetric, and transitive).

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

correct choice is a

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
