Answer:
$333
Step-by-step explanation:
4,000 / 12 is about 333.34
Rounding the .34 down to the nearest whole number (0), we end up with about $333.
2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)
x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x

➷ Use the equation y = mx + c
First we need to find the slope
slope = rise/run
slope = 1/2
Now we know the slope is 0.5
As you can see, the y intercept (where the line crosses the y axis) is 0.5
Therefore, the equation would be y = 0.5x + 0.5

Answer:
A = 502 * e^-(.033 * 68) amount left after 68 rears
A = 502 e^-2.244 = 53.2 grams after 68 years
A2 = 502 e^-(.033 * T) = 251 where T is time for 1 half-life
ln (1/2) = -(.033 * T)
T = -.693 / -.033 = 21.0 years for the half-life
