Find f (2) - 4 using the following equation.
f(x) = 5x – 2
f (2) - 4 =

On this equation it would be 5(2)-2=f(2) which f(2)=8 then 8-4=4.

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
