On a number​ line, the coordinates of​ X, Y,​ Z, and W are negative 8​, negative 6​, 1​, and 5​, respectively. Find the lengths
bogdanovich [222]

Consider the coordinates of​ X, Y,​ Z, and W.

The given coordinates are X= -8​, Y = -6​,Z= -1​ and W= -5.

We have to determine the length of segments XY and ZW.

XY = Y - X = -6-(-8) = -6 + 8 = 2 units

ZW = W - Z = -5-(-1) = -5+1 = -4 units

Since, the length of the segments are not equal.

Hence, XY and ZW are not congruent.

Determine el radio vector del punto medio del segmento que se forma al unir los puntos (-8, 7) y (6, 3).
tiny-mole [99]

Answer:

The radius vector is (-8, 7) and (-1 , 5).

Step-by-step explanation:

Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).

The end points are (- 8, 7) and (6, 3) .

The mid point is given by

x = \frac{x' + x''}{2}\\\\y = \frac{y' +y''}{2}\\\\x =\frac{- 8 + 6}{2}=-1\\\\y = \frac{7+3}{2} = 5

So, the radius vector is (-8, 7) and (-1 , 5).
