always lies on
0 X axis
O Yaxis
Ox=y
O X+Y=0

Answer 1

Answer:

Although hydrogen has the highest calorific value, it is not used as a domestic fuel. It is because hydrogen is a highly combustible and it reacts explosively when it comes in contact with air. ... So, even though hydrogen has the highest calorific value, it is not used as a domestic fuel.

Answer 2

Answer:

The given point of the form = (a, 0)

To find, the point of the form (a,0) always lies on = ?

∴ The given point of the form = (a, 0)

Here, x-co-ordinate = a and y-co-ordinate = 0

∴ The point of the form (a, 0) always lies on x-axis.

Thus, the point of the form (a, 0) always lies on x-axis.
