The answer is: "1" . ________________________________ Explanation: ________________________ To start, we find this coordinates of this "point that splits the segment in half", known as the "half-point"; or, even more formally, known as the "midpoint", using the following "midpoint formula"; in which "M" refers to the "midpoint": ____________________________________ Given two coordinates (points) on a (straight line segment): ______________________________ (x₁, y₁) ; AND: (x₂ ,y₂ ) ;
The midpoint , "M": ___________________________________ M = (x₁ + x₂) / 2 , (y₁ + y₂) / 2 ; ____________________________________
in which: " (x₁ + x₂) / 2 " ; refers to the "x-coordinate" of the midpoint;
AND: "(y₁ + y ₂) / 2 " ; refers to the "y-coordinate" of the midpoint; _______________________________________________________ If given two particular points, use can use point to start with, as long os the second one is used for the next one: ___________________________________________________ So, given: Point A: (4,3) ; 4 = x₁ ; 3 = y₁ ; Pont B: (-2,6) -2 = x₂ ; 6 = y₂ ; ___________________________________________________ The midpoint , "M": ___________________________________ M = (x₁ + x₂) / 2 , (y₁ + y₂) / 2 = ? Substitute the values: _______________________________________________ M = [4 +(-2)] / 2 , (3 + 6) / 2 ;
→ [(4 <span>− 2) / 2 ] , [(3+6) / 2 ] ;
</span>→ (2/2), (9/2) ;
→ (1, 4.5) __________________________________ The midpoint is: (1, 4.5). This very question asks to find the "x-value" of the midpoint, which is "1" . (Since: x =1, y = 4.5). ________________________________________ So, the answer is: "1" . __________________________________________________
The site of the chernobyl nuclear accident in 1986, was at the Chernobyl Nuclear Power Plant, which was located in Ukraine. In terms of cost and casualties, it was the worst nuclear power plant disaster in history.
