which best explains or justifies step 1?
the first step for deriving the quadratic formula from the
quadratic equation, 0 = ax? + bx + c, is shown.
step 1: -c = ax + bx
subtraction property of equality
completing the square
factoring out the constant
zero property of multiplication

55? i think maybe

step-by-step explanation:

the answer would be c:   ax + b = ax + c

step-by-step explanation:

won't that be plagrisim thought?

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)
