Use the y value in equation one and substitute it in equation two.

y=4x-3
y=-x-13

4x-3=-x-13
solve for x
add x to both sides
5x-3=-13
add 3 to both sides
5x=-10
divide both sides by 5
x=-2

Use x=-2 to solve for y in either equation
y=4x-3
y=4(-2)-3
y=-8-3
y=-11

(x, y) = (-2, -11)
Top right is the answer

Hope this helps! :)

Answer:

interpretation of p-value

With the information from the exercise we can deduce that the number of adults in North America who are going to reduce the costs of medical care, considering this as a national priority, are within a probability of 0.045, however the real data tells us that 0.68 of adults are in favor of this reduction

What is 4/7 ÷ 6/9 showing the work
RSB [31]
First flip the second fraction

4/7 divided by 9/6

Next multiply 4 x 9 which is 36

Then multiply 7 x 6 which is 42

Then divide the fraction 36/42

Which since it's not even it would be in decimal form it would be 0.9

Suppose you have a complete, weighted graph with 8 vertices. How many Hamilton Circuits are there in this graph?
Natali5045456 [20]

The number of Hamilton Circuits with 8 vertices are 5040.

Given that, a complete, weighted graph with 8 vertices.

<h3>What are Hamilton Circuits?</h3>

A Hamiltonian circuit is a circuit that visits every vertex once with no repeats. Being a circuit, it must start and end at the same vertex. A Hamiltonian path also visits every vertex once with no repeats, but does not have to start and end at the same vertex.

For N vertices in a complete graph, there will be (n−1)!=(n−1)(n−2)(n−3)…3⋅2⋅1 routes. Half of these are duplicates in reverse order, so there are (n−1)!/2 unique circuits.

A complete graph with 8 vertices would have = 5040 possible Hamiltonian circuits. Half of the circuits are duplicates of other circuits but in reverse order, leaving 2520 unique routes.

Therefore, the number of Hamilton Circuits with 8 vertices are 5040.
