Answer 2

Answer:

The value of x is -3 .

Step-by-step explanation:

Formula of midpoint

$(w , v) = (\frac{x_{2}+x_{1}}{2},\frac{y_{2}+y_{1}}{2})$

As given

point P ( a,2) is the midpoint of the line segment joining the points Q( -5,4) and R(-1,0).

Thus

$x_{1}=-5$

$y_{1}=4$

$x_{2}=-1$

$y_{2}=0$

w = x

v = 2

Put in the midpoint formula

$(x , 2) = (\frac{-1-5}{2},\frac{0+4}{2})$

Take

$x = \frac{-1-5}{2}$

$x = \frac{-6}{2}$

x = -3

Therefore the value of x is -3 .
