Answer:
No solution
Step-by-step explanation:
These are two, parallel lines. You can tell because they have the same slope.
the first line is
y = -.5x + 4
the second line, when rewritten is
x + 2y = -8
2y = -x - 8
y = -.5x - 4
Notice that 45 hours is 3 times the half-life of 15 hours.
After the first 15 hours, 450 g decays to half this amount, 225 g.
After the next 15 (total 30), 225 g decays to 112.5 g.
After the next 15 (total 45), 112.5 g decays to 56.25 g.
