Question

Show graphically that each one of the following systems of equations is in-consistent (i.e. has no solution):
3x – 5y = 20
6x – 10y = – 40

Answer 1

Answer:

which class question is this

Answer 2

Lines do not intersect

Step-by-step explanation:

Given linear equations are  

3x – 5y = 20 ---- (1)

6x – 10y = – 40 ---- (2)

Co-ordinates for equation 1 will be (0, -4), (1, -17/5), (2, -14/5), (3, -11/5).

Co-ordinates for equation 2 will be (0, 4), (1 , -46/10), (2, -18/10), (3, -12/10).

We find that the two lines when plotted on the graph will never intersect. So there are in-consistent. Hence there is no solution.
