In order for the data in the table to represent a function with a rate of change of -8, one must be the value of m? x | y 10 | 27 11 | m 12 | 11 m=2 m=3 m=19 m=35

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
