1. what is the correct reason for each step in the proof? prove: if 2(x2 + 5) = 60, then x = ±5. a. 2(x2 + 5) = 60 a. b. 2x2 + 10 = 60 b. c. 2x2 = 50 c. d. x2 = 25 d. e. x = ±5 e. 

no

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)
