Show that T is a linear transformation by finding a matrix that implements the mapping. Note that x 1, x 2, ... are not vectors but are entries in vectors. Upper T (x 1 comma x 2 comma x 3 )equals(x 1 minus 2 x 2 plus 2 x 3 comma x 2 minus 5 x 3 )

i can you answer this question sweetie!

step-by-step explanation:

70 years.

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

a reflection across the x axis and a 90 degree rotation left and right.
