m = -20

b = 150

Equation: y=-20x+150

Non-Proportional

Negative Slope

Step-by-step explanation:

Paying back 20 dollars/week (constant, m)

Borrowed 150 dollars (Starting position of slope, b)

Non-Proportional Slope

Negative Slope (Started with 150, losing 20 per week)

hm let me think hm think think hm think yes

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
