Which matrix represents the system of equations shown below? 2x - 9y = 12
-5x - 7y = 15

O A.
[2 -9 12
5 -7 15

O B.
1-2 -9 127
5 -7 15

O C.
2 -9 127
-5 -7 15

O D. 13:53
1-2 -9 -121
-5 -7 -15

answer: idk

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
