Solve the following simultaneous linear equations graphically: (1-5)1 x - y = 0 and x + y = 2

Answer» ONG>Answer:

2x−y−4=0 …(i)

y=2x−4

When x=1,y=2×1−4=2−4=−2

When x=2,y=2×2−4=4−4=0

When x=3,y=2×3−4=6−4=2

x= 1 ,2 ,3

y= −2 ,0 ,2

Mark the above points on graph. Join them.

x+y+1=0 …(ii)

y=−x−1

When x=0,y=0−1=−1

When x=−2,y=2−1=1

When x=−1,y=1−1=0

x= −2 ,−1 ,0

y= 1 ,0 ,−1

Mark the above points on graph. Join them.

It is clear from the graph that the two lines intersect at (1,−2).

So the solution of the GIVEN equations are x=1 and y=−2.

The area of the TRIANGLE FORMED by these lines and Y axis =1/2 ×base×height

=1/2×3×1

=1.5sq. units

Hence area of the triangle is 1.5sq. units.

1. A dealer bought an old refrigerator for 9700. He spent 100 on transportation and 1200 on repairs. He then sold the refrigerator for 13200. Find his profit or loss percent.

Answer» ONG>Answer:

CP of the old refrigerator=₹9700

Extra AMOUNT he kept on old refrigerator=₹1200+100

=₹1300

Total amount he kept on the refrigerator= =₹9700+₹1300

=₹11000

SP of the refrigerator=₹13200

He got profit because SP is more than CP

Profit %=SP-CP/CP×100

=₹13200-₹10000/₹10000×100

=3200/10000×100
