A craft club sets a goal to make a certain number of birdhouses in June. After the first week, they checked in with each other to see how much of the goal each had completed Joseph: 1/3 Anna: 1/6 Elvin: 3/12 Theo: 1/4 Marina 5/8 which two members completed the same fraction of the goal? A Marina And Anna. B Elvin and Joseph C Joseph and Theo or DTheo and Elvin?

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

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
