Tina wrote the equations 3x-y=9 and 4x+y=5. What can Tina conclude about the solution to this system of equations?
(3, 2) is a solution to the system of linear equations.
(-2, 3) is a solution to the system of linear equations.
(2.-3) is a solution to the system of linear equations.
(3,-2) is a solution to the system of linear equations.

C. (2,-3) is a solution to the system of linear equations

Step-by-step explanation:

3x - y = 9

4x + y = 5

add

7x = 14

x = 14/7

x = 2

3x - y = 9

3(2) - y = 9

6 - y = 9

-y = 9 - 6

-y = 3

y = -3

Option (C)

Step-by-step explanation:

Solve by Graphing:

Use a graphing tool to graph the lines 3x-y=9 and 4x+y=5.

When graphed, the lines intercept at (2,-3).

Therefore, Tina can conclude that (2,-3) is a solution to the system of linear equations.

congruent segments

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
