Answer: f(x^-1) = x/5 - 3/5
Step-by-step explanation:
1. Replace f(x) with y
2. Swap the positions of x and y to make x = 5y + 3
3. Solve for y by subtracting 3 from both sides and dividing each side by 5
The answer is B. Hope this helps!(:
1/4 saved, 3/4
1/3 of the rest (4/4-1/4=3/4, 3/4=rest)
1/3 of 3/4=3/12=1/4
saved=1/4
spent on t-shirt=1/4
CD=?
1/4+1/4+?=4/4
2/4+?=4/4
minus 2/4
