Ответ:
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18...correct
2x - 2y = 2(2,3)
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2...incorrect
when (2,3) is subbed into equation 1, it is true
when (2,3) is subbed into the second equation, it is false
the ordered pair (2,3) is not a solution to the system of linear equations
Ответ:
When
is substituted into the first equation, the equation is true
When
is substituted into the second equation, the equation is false
The ordered pair
is not a solution to the system of linear equations
Step-by-step explanation:
we have
we know that
If a ordered pair is a solution of a system of linear equations
then
the ordered pair must be satisfy the first and the second equation of the system of linear equations
Statements
case A) When
is substituted into the first equation, the equation is false
The statement is false
Substitute the value of x and the value of y of the point
in the first equation
therefore
the point
is a solution of the first equation
case B) The ordered pair
is a solution to the system of linear equations
The statement is false
Because, the ordered pair
is not a solution of the second equation
Verify
Substitute the value of x and the value of y of the point
in the second equation
therefore
the ordered pair
is not a solution of the second equation
case C) When
is substituted into the first equation, the equation is true
The statement is true
Substitute the value of x and the value of y of the point
in the first equation
therefore
the point
is a solution of the first equation
case D) When
is substituted into the second equation, the equation is false
The statement is true
Substitute the value of x and the value of y of the point
in the second equation
case E) When
is substituted into the second equation, the equation is true
The statement is false
Substitute the value of x and the value of y of the point
in the second equation
case F) The ordered pair
is not a solution to the system of linear equations
The statement is true
Because, the ordered pair
is not a solution of the second equation
