Question

The number of points on x axis which ae at a distance cless than 3 from te point 2,3

Answer 1

Answer:

pls mark me brainliest ans

Step-by-step explanation:

Distance of 'c' units from (2,3)

Let the no: of points be (x,0)

By distance formula

{(2−x) 2+(3−0) 2 }=c

4−4x+x 2 +9=c

⇒x 2−4x+13=c:c=2,2

There are the points of c,such that when they are applied back to the equations,the number of points will become zero .
