tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 710,000 tritium atoms remained undisturbed for 10 years. How much tritium does the bottle contain now?

the first one, all those points on the line just make a strait line.

answer: 4 (:

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

i can answer this if i have the answer choices
