Answer:
194.5315427 grams
Step-by-step explanation:
The half-life of element x would be 66 years. So, after 20 years you would have:
.5^(20/66) x 240=0.810548 x 240
=194.5315427 grams of the element left ......

Ooo.
Fun.
So the equation: y = 1/4x = 3 is in slope-intercept form where, y = mx + b.
'm' is the slope and 'b' is the y-intercept.
Knowing this, we can easily conclude that Choice A is the correct answer.
Why?
Well, just look below.
y=1/4x + 3
y = mx + b
We simply match up the values with the slope-intercept formula and see that 3 falls under the y-intercept category, and m, which always equals slope is replaced by 1/4.
Thus, A is the correct choice.
I think 0 and 1 because it can be right in the number line
