Answer:

(2,7) is not a solution to the given system of equations.

Step-by-step explanation:

Given system of equation is:

2x + 3 = y

2x + y = 15

To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.

Putting x=2 and y=7 in Eqn 1

2(2) + 3 = 7

4 + 3 = 7

7 = 7

Thus the ordered pair satisfies the equation

Putting x=2 and y=7 in Eqn 2

2(2) + 7 = 15

4 + 7 = 15

11 ≠ 15

The ordered pair do not satisfy the second equation.

Hence,

(2,7) is not a solution to the given system of equations.

Help what is the answer for this
grandymaker [24]

Answer:

A) <SQT = 36 degrees

B) <QRW = 36 degrees

C)<PRV = 72 degrees

Step-by-step explanation:

A) <SQT = 36 degrees (< SQT and < PQR are<em> vertically opposite angles</em>, and vertically opposite angles are equal)

B) <QRW = 36 degrees ( <QRW and < SQT are <em>corresponding angles</em> since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)

C)<PRV = 72 degrees( <PRV is the <em>exterior base angle </em>to < PQR and exterior base angles, are always twice their interior correxpondents)
