Question

What is the x-coordinate of this endpoint? Drag the values into the box to correctly complete the table.

Answer 1

Answer:

the correct answer is 4-2√29 & 4+2√29

Step-by-step explanation:

using distance formula:

let line be AB with A coordinate (4,-1) and B coordinate (x,9)….... given

so AB=√(x2-x1)^2+(y2-y1)^2

6√6=√(x-4)^2 +(9+1)^2

6√6=√x^2-8x+116

sqaring both side

we get,x^2-8x-100

now by using quadratic formula we will get two value of x

ie. 4-2√29& 4+2√29
