I really need your help :( you don’t have to explain just tell me the answer XYZ has vertices at (0,0) (6,9) and (15,0) triangle XYZ is dilated by scale factor or 1/3 about origin . WHAT are the coordinates of vertices of the image

tip $2.90

total $17.40

too hard the other guy did it

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
