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).

2(40)+20 = 100m
40+20= 60m
100x60= 6000m
Answer:
Y is going to triple(y1=3y)
Step-by-step explanation:
y=5/x;
x triples means y1=5/(3x);
Y1 divided by y, we get (5/x)/(5/3x)=(5/x)*(3x/5)=3
Answer:
C
Step-by-step explanation:
Since the vertex is 2,1, that's the only equation that works for it. The 2 has to be the opposite, so -2, and the 1 stays 1.
