Answer:
(-2,-3/2)
Step-by-step explanation:
Midpoint formula=(x1+x2/2, y1+y2/2)
So...
(3+-7/2, -5+2/2) =
(-2, -3/2)
Answer:
a(n) = 9.5 + 2(n - 1)
Step-by-step explanation:
Observe that each new term is obtained by adding 2 to the previous term. Thus, the common difference is 2 and the first term is 9.5.
Then a(n) = 9.5 + 2(n - 1)
There are 10 millimeters in 1 centimeter. one millimeter is one-tenth of a centimeter.
Using two points to find the slope use
y2-y1/x2-x1
i chose points (0,4) and (2,14)
14-4/2-0
10/2
5
The slope is 5
The amount of ways would be :
9! / (9-3) !
= 9 ! / 6 !
= 9 x 8 x 7
= 504
The answer is option B,
hope this helps
