Rewrite the equation below so that it does not have fractions.
lidiya [134]

Answer:

\frac{15}{20} x-2=\frac{8}{20}

Step-by-step explanation:

\frac{3}{4} x-2=\frac{2}{5}

3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that

\frac{3}{4} =\frac{15}{20}

\frac{2}{5} =\frac{8}{20}

\frac{15}{20} x-2=\frac{8}{20}

You can then multiply both sides by twenty to solve this equation.

Hope this helps.

How do the graph of f(x) and f^-1(x) relate?
weeeeeb [17]
<h2>SOLVING</h2>

\Large\maltese\underline{\textsf{A. What is Asked}}

How do the graphs f(x) and f^-1(x) relate?

\Large\maltese\underline{\textsf{B. This problem has been solved!}}

These two functions are inverses of each other.

That's the way these two are related to each other.

f^-1(x) is the inverse function of f(x), and f(x) is the inverse function of f^-1(x).

\rule{300}{1.7}

\bf{Result:}

            \bf{=They\;are\:inverses}

\boxed{\bf{\space aesthetic \space \not101}}
