The midpoint of pq is (–6, –3). one endpoint of pq is p(–1, –4). what are the coordinates of q? a. q(–11, –2) b. q(–3.5, –3.5) c. q(2, 11) d. q(11, 2)

The coordinates of the midpoint of the line segment is the average of the coordinates of both end points. For this example above, let (x, y) be the coordinates of point Q. 

                     (abscissa)   -6 = (-1 + x) / 2       ; x = -11
                     (ordinate)    -3 = (-4 + y) / 2       ; y = -2

Therefore, the coordinates of point Q is (-11, -2). The answer is letter A. 

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
