Answer:
x = -4 / 3
Step-by-step explanation:
step 1. simplify 4x2 to 8
8+6x=0
step 2. subtract 8 from both sides.
6x = -8
step 3. divide in both sides by 6.
x = - 8 / 6
step 4. simplify 8/6 to 4/3.
x = -4 / 3
To know the initial amount of the radioactive substance, you should read the graph in the y - axis when the x = 0, because at x = 0 this means the intial point of the graph or the initial amount of the substance. so at x = 0 the y = 45 so the initial amount is 45 g
