Solve the system by graphing or using a table. 2x+4y=12 x+y=2

x = -2 and y = 4

Step-by-step explanation:

We have given a system of equations

2x + 4y =12   ...........(1)

and

x + y = 2         .............(2)

Now to plot them in graph we need to find the points of the above linear equations .

From equation 1  ,we get

So get the points (0,3) and (6,0).

From equation 2 ,we get

So we get the points (0,2) and (2,0).

So after plotting these points we get two lines intersecting at (-2,4).

Therefore our solution is x=-2 and y= 4.

which expression represents the approximate length of bc?

step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12
