PLEASE HELP ME !! EASY 25 POINTS! WILL MARK AS BRAINLIEST If you need any more info, please let me know. 4. Christina made a graph to describe the distance she walked on her back packing trip. She plotted miles on the y-axis and the number of days on the x-axis. She graphed a point at (0,0) and another point to show she walked 14 miles in 8 days and drew a line that passes through the points. What is the slope of the line?

The image of the point (-6, -2)under a translation is (−7,0). find the coordinates of the image of the point (7,0) under the same translation.

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
