Answer: f(x)=3/2×-2
Step-by-step explanation:
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
The answer is $70 so D
Because $59.5 is 85% of the original price, use 59.5/0.85 to find the original price
