What is the image of (0,-4) after a dilation by a scale factor of 1/2 centered at the origin?

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

answer:   2 multiplied by x =24

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
