x=35

Step-by-step explanation:

Since x is 14 when y is 2, you can set up a proportion to show this. It would be 14/2, and you can simplify this to 7/1. This means x is 7 when y is 1.

Y is 5, not 1, so if we multiply the proportion on both sides by 5, we will get the answer. 7/1 would turn into 35/5.

So, x is 35 when y is 5.

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
