An experiment was conducted that recorded the weight of a new bar of soap after each use. The line of best fit for the data collected is y = - 5 -5.6x 6x + 123 , where y is the weight of the bar of soap, in grams, and ris the number of times that the bar was used Which statement describes the meaning of the -intercept for the line of best fit equation ?

c) yes, because of asa or aas

step-by-step explanation:

no solution.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
