Question

Help please!!!! !!!!!!!

Answer 1

We have two equations y = -2x+4 and 7x-2y = 3. We have an ordered pair (1,2).

Let's plug this value in the equations and check if it is true or not.

First equation: y = -2x+4

2 = -2(1) +4

2 = -2 +4

2 = 2

It is True.

Second equation: 7x-2y = 3

7(1) - 2(2) = 3

7 - 4 = 3

3 = 3

It is True.

So we can select following options:

Option B: When (1,2) is substituted into the first equation, the equation is true.

Option E: When (1,2) is substituted into the second equation, the equation is true.

Option F: The ordered pair (1,2) is a solution to the system of linear equations.

Answer 2

Answer:

Option 2, 5 and 6.

Step-by-step explanation:

We have two equations:

$y = -2x + 4$ --- (i)

$7x - 2y = 3$ --- (ii)

By substituting the values of the given ordered pair (1, 2), we can check if it is their solution or not.

For y = -2x + 4:

2 = -2(1) + 4

2 = 2 ∴ It is true

For 7x - 2y = 3:

7(1) - 2(2) = 3

7 - 4 = 3

3 = 3 ∴ It is true

Based on these results for both the equations, the following are the correct answer options:

2. When (1, 2) is substituted into the first equation, the equation is true.

5. When (1, 2) is substituted into the second equation, the equation is true.

6. The ordered pair (1,2) is a solution to the system of linear equations.
