5 0

Answer:

Step-by-step explanation:

4x + 7y - 3x - y

Move like terms next to each other.

4x - 3x + 7y - y

Subtract them

4x-3x= 1x or x

7y-y = 6y

So we have:

x + 6y

A certain connected graph has 68 vertices and 72 edges. Does it have a circuit?
OLEGan [10]

Answer:

Yes.

Step-by-step explanation:

If a graph G doesn't have a circuit, we must have that

|E(G)|=|V(G)|-1

where |E(G)| is the number of edges of the graph and |V(G)| the number of vertices. However, in this case it holds that

|E(G)|=72>68=|V(G)|.

➷ We have 2 points which we can use to figure out the slope

slope = difference in y values/ difference in x values

Substitute in the values you have:

0 - 5/ 3 - 0

slope = -5/3

The y intercept is simply where the line crosses the y axis

In this case, it is 5

Therefore, your equation is y = -5/3x + 5

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Charra [1.4K]

Answer:

7/9 or ~77.7778% or 0.777778

Step-by-step explanation:

First you need to find the total amount or marbles.

  • 8+4+6=18

Next, find the sum of <em>just</em><em> </em>the<em> </em>blue<em> </em>and red marbles.

  • 8+6=14

Now, find the probability by dividing or simplifying the number of blue and red by the total.

  • 14/18= <u>7/9</u> OR <u>~</u><u>0</u><u>.</u><u>7</u><u>7</u><u>7</u><u>7</u><u>7</u><u>8</u>

"Which equation has no solution?
faust18 [17]
The equations without a solution are A, B, and D since if you were to simply multiply out the equations with FOIL, you would receive X's that cancel out on both sides. I am not sure if you are looking for one solution but here's my input
