Which statements are true about the ordered pair

Lostsunrise [7]

Answer:

-The ordered pair (-1, 5) is a solution to the first equation because it makes the first equation true.

-The ordered pair (-1, 5) is a solution to the second equation because it makes the second equation true.

-The ordered pair (-1, 5) is a solution to the system because it makes both equations true

Step-by-step explanation:

The correct question is

Which statements are true about the ordered pair (−1, 5) and the system of equations?

x+y=4

x−y=−6

we know that

If a ordered pair is a solution of a equation, then the ordered pair, must satisfy the equation (makes the equation true)

If a ordered pair is a solution of the system of equations, then the ordered pair, must satisfy the equations of the system (makes both equations true)

we have

$x+y=4$ ----> first equation

$x-y=-6$ ----> second equation

step 1

Verify if the ordered pair satisfy the first equation

Substitute the values of x and y of the ordered pair in the first equation

For x=-1, y=5

$-1+5=4$

$4=4$ ---> is true

The ordered pair satisfy the first equation

The ordered pair is a solution to the first equation because it makes the first equation true

step 2

Verify if the ordered pair satisfy the second equation

Substitute the values of x and y of the ordered pair in the second equation

For x=-1, y=5

$-1-5=-6$

$-6=-6$ ---> is true

The ordered pair satisfy the second equation

The ordered pair is a solution to the second equation because it makes the second equation true

therefore

The ordered pair (-1, 5) is a solution to the system because it makes both equations true

1. What is the sum of the polynomials?

AysviL [449]

Answer:

1. 2m+2n+7

2. 3m-2

3.-2m+2-2n

Explanation:

To find the sum of given polynomials (m+n+3) +(m+n+4)

Firstly, open the parenthesis we will get m+n+3+m+n+4

After simplification we will get 2m+2n+7

To find the difference of given polynomials (10m-6)-(7m-4)

Firstly, open the parenthesis we will get 10m-6-7m+4

After simplification we will get 3m-2

Again to find the difference of the polynomials (4m-5)-(6m-7+2n)

Firstly, open the parenthesis we will get 4m-5-6m+7-2n

After simplification we will get -2m+2-2n

aliina [53]

Answer:

1st blank: X axis reflection

2nd blank: Y axis reflection

Step-by-step explanation:

If you drew the first triangle and then the second triangle on a piece of paper, you would notice that it would reflect across the corresponding axis.

So the solution is to just draw it out.

ASAP! GIVING BRAINLIEST! Please read the question THEN answer correctly! No guessing. Show your work or give an explaination.

Eddi Din [679]

<h3>Answer: x = $\frac{1}{3k}$ </h3>

Step-by-step explanation:

Subtract 6kx from 30kx to get 24kx = 8.
divide both sides by 24kx: $\frac{24kx}{24k}$ = $\frac{8}{24k}$
That leaves us with $\frac{1}{3k}$ .
