The mass of a sample of the chemical element Einsteinium-253 after it is initially measured is represented by the following table. Time( weeks)=
0
3
6
9
12
15

Mass(grams)=
400
201
98
50
24
12

Which model for M(t), the mass of the sample t weeks after it’s initially measured, best fits the data?

Choose 1 answer=
A= M(t)=400•(0.5)^ t
B= M(t)=400•(0.79)^ t
C=M(t)=400-200• t
D=M(t)=400-12• t

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

it is x=-4
