M is the midpoint of CD. C has coordinates (-1, -1) and M has coordinates (3, 5). Find the coordinates of D.
o (-5, -7)
O (4, 6)
O (6, 10)
0 (7, 11)

(7, 11)

Step-by-step explanation:

If a line segment has endpoints at A() and B(), the coordinates of the midpoint O(x, y) of the segment AB is given by the formula:

Given the midpoint M(3, 5) of the segment CD with the coordinates of C at (-1, -1). Let the coordinates of D be at (). Hence:

Hence the coordinates of D is at (7, 11)

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
