Question

A is a point on x axis and B is (-7, 9).distance between them is 15 units. Find coordinates of A

Answer 1

Answer:

coordinates of A=(-19,0) or (5,0)

Step-by-step explanation:

A is a point on the x axis

So the ordinate( value of y axis) is 0

let coordinate of A=(x,0)

coordinates of B= (-7,9)

BY USING DISTANCE FORMULA

$\sqrt ((x+7)^2) +( 0-9)^2$

Solve it further..please

You will have a quadratic equation with 2 values of x which are -19 and 5

Hence, coordinates of A=(-19,0) or (5,0)
