The equation is d = 67*d (Distance = speed*time).
The table is
h d
1 67
2 134
3 201
4 268
.......
Answer:
f(x)= x2 -4
Step-by-step explanation:
it is because it has no complex roots
Midpoint = (x1 + x2) / 2, (y1 + y2)/2
(-2,1)....x1 = -2 and y1 = 1
(4,-1)...x2 = 4 and y2 = -1
time to sub
m = (-2 + 4) / 2 , (1 + (-1) / 2
m = (2/2), (0/2)
m = (1,0) <==
y = -x + 1.....(1,0)...x = 1 and y = 0
0 = -1 + 1
0 = 0 (correct)
so the midpoint M (1,0) lies on the line since its coordinates satisfy the equation <===
Pythagorean Theorum since that is what you are trying to prove.
