Point c is on the segment ab which has endpoints a(2,-1) and b(11,5). point c is twice as far from point a as it is from point b. what are the coordinates of point c

The line is divided in the ration 2:1.

The formula for the x coordinate of c is:-

x =   2*1 + 11*2  / (2+1) =  24/3 = 8

y =  -1 *1 + 5*2 /  3 =   9/3 = 3

Coordinates of c are (8,3)  answer

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
