The statement explains why the ordered pair is a solution to the system of equations. Is the statement true or false? True False

The ordered pair (−3,−6) is a solution for the first equation, and it is a solution for the second equation. Therefore, (−3,−6) ​ is a solution to the system of equations. ​ −4x y=65x−y=21 ​.

The system of the equation doesn't give the solution at (-3, -6).

<h2>Given to us</h2>
  • -4x+y = 6
  • 5x-y =21

<h3>Equation 1,</h3>

-4x+y = 6

solve for y

-4x+y =6\\y= 6+4x

<h3>Equation 2,</h3>

5x-y =21

substitute the value of y in equation 2,

5x-(6+4x) =21\\5x -6 -4x =21\\5x -4x=21+6\\x = 27

Substitute the value of x in equation 2,

5x-y =21\\5(27)-y =21\\135-y = 21\\-y=21-135\\-y = -114\\y=114

We can see that the solution of the two equations is at (27, 114). Also, it can be verified by plotting the line on the graph.

Hence, the system of the equation doesn't give the solution at (-3, -6).

musickatia [10]

Answer:

7,897.30 miles

Step-by-step explanation:

It is given that the North Pole is at a distance of 3,949 miles from the center of the earth.

We also know that the sea floor is below 2.4 miles from the sea level.

It is given that a submarine is located at the sea floor near North Pole. Hence, the distance of the submarine from the center of the earth would be

3949 - 2.4 = 3946.6 miles.

On the other hand, the South Pole is given to be at an elevation of 1.7 miles from the sea level.

Since we know that the sea level is at a distance of 3949 miles from the center of the earth, we can immediately calculate the distance of the South Pole from the center of the earth to be

3949 + 1.7 = 3950.7 miles.

Putting all of this together, we see that the center of the earth is at a distance of 3946.6 miles from the submarine near the North Pole, and the center of the earth in turn is 3950.7 miles from the South Pole.

Hence, the distance between the submarine and a person on the South Pole = 3946.6 + 3950.7 = 7897.3 miles.
