Look at the two equations: -3x + 6 = 21 -3x + 621 Which statement best describes the process used to solve the equations? A. In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
B. In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.
C. The process is exactly the same for solving the equation and solving the inequality.
D. The process for solving the equation is entirely different from solving the inequality.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
