Algebra.Com's Answer #499772 by josgarithmetic(39627) ![]() You can put this solution on YOUR website! Some thought should give you how to see this is a system of linear equations, two variables.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x=0 for time NOW. Number of bugs is y, and number of months is x.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Ladybugs: slope is 2 and y intercept is 15. The equation is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Aphids: slope is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "WHEN do these two equations have the same point, or, what is the intersection point? \n" ); document.write( " \n" ); document.write( "SOLVE FOR x. \n" ); document.write( " |
