X+x+2+x+4+x+6+x+8 < 100
5x + 20 < 100
5x < 80
x < 16

so the 5 numbers are 14,16,18,20,22 and maximum sum = 90

100/5 = 20

would be the middle number so 18 +19+20+21+22 = 100

since you want it to be less than 100 use 17 instead of 22

so you have 17 +18+19+20+21 = 95

95 is the maximum sum

If another line is perpendicular to the line shown on the graph, what must be its slope

Shtirlitz [24]

It's B

Slope is negative, the other must be positive due to m1 x m2 = - 1

m1 = -2/5

The diagram shows a gradient of -2/5. So, the

reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)

-2/5 x 5/2 = - 10/10 (or - 1)

Thus, the perpendicular line to this has a gradient of 5/2.

Hope this helps!

The degree of a vertex is Help please

Nina [5.8K]

Answer:

is the number of graph edges which touch v

Step-by-step explanation:

To find the degree of a graph, figure out all of the vertex degrees. The degree of the graph will be its largest vertex degree. The degree of the network is 5.

Once you know the degree of the verticies we can tell if the graph is a traversable by lookin at odd and even vertecies. First lets look how you tell if a vertex is even or odd.

Snowcat [4.5K]

Answer:

7

Step-by-step explanation:

So:a=3

b=(-2)

c=2

Substitute the numbers into each letters

so a is represented by 3,c by 2 and b -2

therefore giving us: 2

3+(-2)=9+(-2)=7
