A system of linear equations has been graphed in the diagram. determine a reasonable solution for the system of equations.
Grace [21]

Answer:

(1,-1)

Step-by-step explanation:

The solution to a system of equation means the x and y values if we were to solve both equations (of lines) simultaneously.

That is also known as the intersecting points.

The top-right part is known as the 1st Quadrant in a coordinate system.

Top-left is 2nd Quadrant.

Bottom left is 3rd Quadrant.

Bottom right is 4th Quadrant.

The values of x and y (positive or negative) of each quadrant is shown below:

  • Quadrant 1: x +ve, y +ve
  • Quadrant 2: x -ve, y +ve
  • Quadrant 3: x -ve, y -ve
  • Quadrant 4: x +ve, y -ve

The intersection point (solution) of the 2 lines shown is in the 4th quadrant, which has x values positive and y values negative.

From the answer choices, we see that 3rd answer choice goes with this -- (1,-1), so this is the correct choice.

Find the angle measure that of each missing angle
11111nata11111 [884]

Step-by-step explanation:

122+v=180

v=180-122

v=58

w+61=180

w=180-61

w=119

61+58+y=180

119+y=180

y=180-119

y=61

61+x=180

x=180-61

x=119

j=180

Please help me solve this
grigory [225]

Answer:

The length of river D is 2550

length of river C is 2550+500=3050

Step-by-step explanation:

Let the river D be 'x'

and the river C is (x+500)

x + x + 500 = 5600

2x + 500 = 5600

2x = 5600 - 500

2x = 5100

x = 5100/2

x = 2550

The length of river D is 2550

length of river C is 2550+500=3050
