Answer:
(-20, 19)
Step-by-step explanation:
We need to use the Midpoint Formula, which says that given two points
and
, the midpoint is
.
Here, we are given one of the endpoints and the midpoint:
endpoint S = (5, -8)
midpoint M = (-7.5, 5.5)
Plug these into the formula. In
, x1 = 5, and this whole expression is equal to -7.5:

Solve for x2:
5 + x2 = 2 * (-7.5) = -15
x2 = -15 - 5 = -20
Now, let's find y2. y1 is just -8, and the entire expression for the y-coordinate of the midpoint is equal to 5.5. So:

Solve for y2:
-8 + y2 = 2 * 5.5
-8 + y2 = 11
y2 = 11 + 8 = 19
The coordinates of T are thus (-20, 19).

Answer:
Step-by-step explanation:
2x - 2 = -18
To cancel the -2, add 2 to both sides.
2x = -16
Divide both sides by two to isolate the x.
X = -8
