To find f^{-1} (x), you can switch the x and the y(which is f(x)).

So instead of f(x)=\frac{-7}{4x-5}, it will be:

x = \frac{-7}{4y-5}

Now you need to find "y".

You first multiply (4y - 5) on both sides

x(4y - 5) = -7

Next divide "x" on both sides

4y - 5 = \frac{-7}{x}

Add 5 on both sides

4y = \frac{-7}{x} +5

Divide 4 on both sides to get "y" by itself

y = \frac{7}{4x} +\frac{5}{4}


f^{-1} = \frac{7}{4x} +\frac{5 }{4}

Is 55000 mg greater than, less than, or equal to 2 kg?
seraphim [82]
1 kg = 1,000,000 mg

55,000 mg = 55,000/1,000,000 = 0.055 kg

0.055 kg < 2 kg

so  55,000 mg < 2 kg
