Asystem of equations is graphed on the coordinate plane. y=−2x−4y=2x+4 what is the solution to the system of equations? enter the coordinates of the solution in the boxes. ( , )

Answer-

The coordinates of the solution is (-2, 0)

Solution-

System of equations are,

  -----------------1

  -----------------2

Putting the value of y from equation 1 in equation 2,

Putting the value of x in equation 1,

Therefore, the coordinates of the solution is (-2, 0)

answer: two five pound bags one two pound

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
