WILL GIVE THANKS AND BRAINLIEST!!
−12x+14x−6x
if x=129.

-516

Step-by-step explanation:

Way #1

Step 1:  Plug in x into the equation

-12(129) + 14(129) - 6(129)

-1548 + 1806 - 774

-516

 -516

Way #2

Step 1:  Or the other way is to simply the equation then plug x in.

-12(x) + 14(x) - 6(x)

-18x + 14x

-4x

Step 2:  Then plug in x

-4(129)

-516

 -516

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)
