the statement explains why the ordered pair is a solution to the system of equations. is the statement true or false?
the ordered pair (−4,−1) is a solution to the system of equations because when (−4,−1) is substituted into the equation, both equations are true.
3x+8y=20
−5x+y=19
true or false?

False,

(-4, -1) is not a solution of the given system of equations

Step-by-step explanation:

Given the system of equations:

           .......[1]

             ......[2]

To determine (-4, -1) is a solution

Substitute x = -4 and y = -1 in both the equations, if they both satisfied then it is a solution.

⇒

⇒         False.

⇒

⇒             True.

Since, the given statement is not true

because the ordered pair (-4, -1) does not satisfy the given system of equations.

False

Step-by-step explanation:

Given : The ordered pair (−4,−1) is a solution to the system of equations because when (−4,−1) is substituted into the equation, both equations are true.   and

To find : Is the statement true or false?

Solution :

Let the equations,

.....Equation (1)

.......Equation (2)

Now, We have to determine that (-4,-1) is a solution of equations or not.

Substitute (-4,-1) in equation (1)

False, The point is not satisfied the equation.

Substitute (-4,-1) in equation (2)

True, The point is satisfied the equation.

Since, The statement given is not true as ordered pair(-4,-1) is not satisfying the equation.

Therefore, The answer is false.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
