Question

f point C is the midpoint of /AB , what is the coordinate of point B?

(–9, 2)

(–3, 1)

(0, –7)

(–1, –8)

Answer 1

mid-point again LOL

Answer 2

read pages 2 and on - http://finedrafts.com/files/Larson%20PreCal%208th/Larson%20Precal%20CH1.pdf

Answer 3

mid-point formula is in page 5

Answer 4

so is A

Answer 5

plz is it

Answer 6

did you also read about the distance?

Answer 7

yes

Answer 8

bout c

Answer 9

\[\large Midpoint(x,y) = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\]


Here: \((x,y) = (-3, -5)\) , \((x_1, y_1) = (-6, -3)\) and we have to find \(x_2\) and \(y_2\)


\[\large Midpoint(-3,-5) = (\frac{-6 + x_2}{2}, \frac{-3 + y_2}{2})\]

Try to equate x coordinate of Left side with the right side..

Similary do for y coordinates on both the sides.. and find \(x_2\) and \(y_2\)...

Answer 10

ok so is should be A or c

Answer 11

for x, what do you need to add to -6 so when you divide it by 2, you get -3? the same technique for y.

Answer 12

Simply solve this:

\[\frac{-6 + x_2}{2} = -3\]

Multiply 2 both the sides and then add 6 both the sides and tell me what are you getting for \(x_2\)..

Answer 13

D,

[-6+(-9)]/2 = -3?

Answer 14

What is this @panlac01

asking her why she's choosing A as an answer.

Answer 16

indirectly, of course
