In which of the tables below x and y are inversely proportional? Find the constant of variation. (a)
x 3 4 5 5.5
y 8 6 4.8 4

(b)
x 0.1 0.5 75 100
y 300 60 0.4 0.3

PLZ HELP ASAP WILL MARK BRAINLEIST I PROMISE

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer

Add, subtract, multiply, or divide as indicated. list any restrictions for the variable(s) and simplify the answers when possible. 1) x-2 / x+5 + 3x / 2x-1 2) x+6 / x-6 - x^2 / x+6 3) x+9 / x-4 + x+2 / x^2-11x+28 4) x / x^2-64 + 11 / 2x^2+11x-40 5) 5 / x + 11 / x-3 - x-4 / x^2+2x-15
