Answer:

Step-by-step explanation:

a). 1\frac{3}{5}=1+\frac{3}{5}

         =1+\frac{3}{5}\times \frac{4}{4}

         =1+\frac{12}{20}

         =1\frac{12}{20}

   1\frac{3}{4}=1+\frac{3}{4}

        =1+\frac{3}{4}\times \frac{5}{5}

        =1+\frac{15}{20}

        =1\frac{15}{20}

Therefore, common denominator of 20.

b). 2\frac{1}{2}=2+\frac{1}{2}

         =2+\frac{1}{2}\times \frac{5}{5}

         =2+\frac{5}{10}

         =2\frac{5}{10}

     \frac{4}{5}=\frac{4}{5}\times \frac{2}{2}

        =\frac{8}{10}

Common denominator of 10.

c). \frac{3}{8}=\frac{3}{8}\times \frac{6}{6}

       = \frac{18}{48}

   \frac{1}{6}=\frac{1}{6}\times \frac{8}{8}

      = \frac{8}{48}

Common denominator of 48.

Identify the oblique asymptotes of f(x)=2x^2-5x+2 over x-3
kondor19780726 [428]
\bf \cfrac{2x^2-5x+2}{x-3}\qquad &#10;\begin{array}{r|rrrrll}&#10;3&2&-5&2\\&#10;&&6&3\\&#10;--&--&--&--\\&#10;&2&1&5&#10;\end{array}&#10;\\\\\\&#10;quotient=\underline{2x+1}\qquad remainder=5&#10;\\\\\\&#10;\textit{thus oblique asymptote is }y=\underline{2x+1}

oblique/slant asymptotes occur when the degree of the numerator is exactly 1 greater than that of the denominator

and the oblique asymptote occurs at the quotient of the rational expression, notice, since the denominator is just x - 3, doing a quick synthetic division will do to get the quotient.
