If said number is x, that means that twice (2 times) a number and 2x-7=13. Adding 7 to both sides, we get 2x=20 and by dividing both sides by 2 we get x=10. For 2, we see that the sum of a number and 6 is first priority, so we have (x+6)*7=-43. Dividing both sides by 7, we get x+6=-43/7. After that, we subtract both sides by 6 to get -43/7-6=x

If f(x)=2x+1/x Find f^-1(x)
Masteriza [31]

Answer:

• Let f(x) be m

m =  \frac{2x + 1}{x}  \\  \\ mx = 2x + 1 \\  \\ mx - 2x = 1 \\  \\ x(m - 2) = 1 \\  \\ x =  \frac{1}{m - 2}

Therefore:

{ \boxed{ {f}^{ - 1} (x) =  \frac{1}{x - 2} }} \\
