Use algebra to find the point at which the line k(x) = -1/2 x + 25/8 intersects the line h(x) = 5/4 x + 155/16. \r
\n" ); document.write( "\n" ); document.write( "We're solving 2x2 systems using graphing but I don't recognize the k(x) and the h(x).
\n" ); document.write( "-------------
\n" ); document.write( "k(x) and h(x) are functions of x.
\n" ); document.write( "To graph them, replace them with y:
\n" ); document.write( "y = -x/2 + 25/8
\n" ); document.write( "y = 5x/4 = 155/16
\n" ); document.write( "Same thing.
\n" ); document.write( "-----
\n" ); document.write( "Since they both equal y (or the function h(x) & k(x) are equal at the intersection),
\n" ); document.write( "-x/2 + 25/8 = 5x/4 + 155/16
\n" ); document.write( "Step 1, eliminate fractions - multiply by 16
\n" ); document.write( "-8x + 50 = 20x + 155
\n" ); document.write( "-105 = 28x
\n" ); document.write( "x = -15/4
\n" ); document.write( "-------
\n" ); document.write( "Sub for x in any function or eqn to find y, and h(x) & k(x)
\n" ); document.write( " \n" ); document.write( "
\n" );
