Answer:
d = 5
Step-by-step explanation:
-7d = -35
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, d. Divide - 7 from both sides:
(-7d)/-7 = (-35)/-7
d = -35/-7
d = 35/7
d = 5
d = 5 is your answer.

Answer: The required co-ordinates of point T are (13, -6).
Step-by-step explanation: given that S is the midpoint of the line segment RT, where the co-ordinates of point R are (-9, 4) and that of S are (2, -1).
We are to find the co-ordinates of point T.
We know that
the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by
Let (h, k) be the co-ordinates of point T. Then, according to the given information, we have
and
Thus, the required co-ordinates of point T are (13, -6).
