Step-by-step explanation:
the midpoint between 2 points (x1, y1) and (x2, y2) is simply ((x1+x2)/2, (y1+y2)/2).
so,
1.
(9, 7) to (4, -3)
midpoint is ((9+4)/2, (7+ -3)/2) = (13/2, 4/2) = (6.5, 2)
2.
(-7, -5) to (2, 1)
midpoint is ((-7+2)/2, (-5+1)/2) = (-5/2, -4/2) = (-2.5, -2)
3.
now we have the midpoint and need the second point.
(4, 2) over (3, 4) to (x, y)
3 = (4 + x)/2
6 = 4 + x
x = 2
4 = (2 + y)/2
8 = 2 + y
y = 6
4.
(-2, 1) over (-3, 2) to (x, y)
-3 = (-2 + x)/2
-6 = -2 + x
x = -4
2 = (1 + y)/2
4 = 1 + y
y = 3
16 x8 will be the new lenth!
Answer:
2x³ - 6x² - x
Step-by-step explanation:
Divide each term in f(x) by g(x), that is
- -
= 2 - 6 -
= 2x³ - 6x² - x
Because b - a could be, for example, b = 5 and a = 7. So if the question were to be 5 - 7 = -2, that would be b - a. If you swap it around, then the question would be 7 - 5 = 2, and that would be a - b. I hope this helps.
