Which situation could NOT represent A proportional relationship (NO SCAMMING PLEASE)
♡´･ᴗ･`♡

F. The Number of gallons of water and X barrels with 42 gallons of water in each barrel.
G. The amount on employee who makes $8.50 per hour earns in h hours.
H. The weight in X weeks of a puppy that gains 2 pounds per week if it’s starting weight 8 pounds
J. The cost of purchasing P pounds of bananas for $0.55 per pound.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

hope this !

let me know

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
