Could you explain how you got the answer

1) 3

2) 5/4

3) 5/9

Step-by-step explanation:

1) Change the sign to multiplication and change 1/4 into it's reciprocal which is 4/1. Multiply 3/4 · 4/1 to get 12/4.

Simplifies to 3

2) Change the sign to multiplication and find the reciprocal of 1/2 which is 2/1. Multiply 5/8 · 2/1 to get 10/8

Simplifies to 5/4

3) First, change the sign to multiplication then find the reciprocal of 3/4 which is 4/3. Multiply 5/12 · 4/3 to get 20/36.

Simplifies to 5/9

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
