Mathematics
1 answer:
N76 [4]4 years ago
8 0

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

For this case we have the following vector:
 v = (- 8, 2)
 Using product point we have:
 v.v = (-8, 2). (- 8, 2)
 v ^ 2 = (-8) * (- 8) + (2) * (2)
 v ^ 2 = 64 + 4
 v ^ 2 = 68
 v = root (68)
 v = root (4 * 17)
 v = 2 * root (17)
 Answer:
 
v = 2 * root (17)

Answer:

(-7.5, 3.5)

Step-by-step explanation:

midpoint \:  = ( \frac{x1 + x2}{2} \:  , \:  \frac{y1 + y2}{2} )

= ( \frac{ ( - 5) + ( - 10)}{2} , \frac{(5) + (2)}{2} )

= ( \frac{ - 15}{2} , \frac{7}{2} )

= ( - 7.5,3.5)
