Answer:
A) 1/2
Step-by-step explanation:
2 up and 4 right
2/4
1/2
It can't be -1/2 because the line is going up and not down.
Step-by-step explanation:
The chromatic number of a graph is the smallest number of colors needed to color the vertices of so that no two adjacent vertices share the same color (Skiena 1990, p. 210), i.e., the smallest value of. possible to obtain a k-coloring. Minimal colorings and chromatic numbers for a sample of graphs are illustrated above ...

Use Picture Math, i cant type in the other cause brainly doesn't accept it but it is Ga_thMath. (u)
For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
