Step-by-step explanation:

Step 1: Define

Identify

f(x) = 3ˣ + 10x

g(x) = 2x - 4

Step 2: Find

Substitute in function values:                                                                          (f - g)(x) = 3ˣ + 10x - (2x - 4)[Distributive Property] Distribute negative:                                                    (f - g)(x) = 3ˣ + 10x - 2x + 4Combine like terms:                                                                                         (f - g)(x) = 3ˣ + 8x + 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
