Find the point on the x-axis which is equidistant from (2,-5) and (-2,9) also draw the diagram |
|
Answer» Answer: Now,the point is on x-axis,so the value 'y' of the given point will be zero. Let,the value of the 'x' value of the given point = x So,the point is = (x,0) As MENTIONED in the question,the two POINTS are EQUIDISTANT from (x,0). So, DISTANCE between (x,0) and (2,-5) = ✓(x-2)²+(0+5)² Distance between (x,0) and (-2,9). =✓(x+2)²+(0-9)² Now,the points are equidistant. So, ✓(x-2)²+(0+5)² = ✓(x+2)²+(0-9)² (x-2)²+(0+5)² = (x+2)²+(0-9)² x²-4x+4+25 = x²+4x+4+81 x²-4x-x²-4x = 4+81-4-25 -8x = 56 x = -7 Hence,the point on x-axis is (-7,0). I am using my COMPUTER so I can't send you the diagram......... |
