Rectangle ABCD is rotated 180°. What rule shows the input and output of the rotation, and what is the new coordinate of A? (x, y) (-x. -y): A' is at (5, -1)
(x, y) – (-y, X), A' is at (-1,-5)
(X, Y) – (y -x); A' is at (1.5)
(x, y) - (x -y): Al is at (-5. -1)

Write an equation for the function that includes the points (2,100)and (3,100)

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
