T is the midpoint of [AB]. Find the coordinates of A. If T is (4,-3) and, B is (-2,3).

A(10, -9)

Step-by-step explanation:

The relation between coordinate of point A(Ax, Ay), point B(Bx, By), and midpoint T(Tx, Ty) of segment line AB is expressed by formula:

Ax + Bx = 2Tx

Ay + By = 2Ty

=>

Ax + (-2) = 2 x 4

Ay + 3 =2 x (-3)

=>

Ax - 2 = 8

Ay + 3 = -6

=>

Ax = 8 + 2

Ay = -6 - 3

=>

Ax = 10

Ay = -9

=> A(10, -9)

Hope this helps!

your answer would be 12

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
