Algebra.Com's Answer #147136 by strickjh2005(4)![]() ![]() ![]() You can put this solution on YOUR website! Look at the basic linear equation; Y=mX+b \n" ); document.write( "Your given equation is using different variables, but in a very similar form. \n" ); document.write( "The slope is 2.85 and the y intercept is given as B (30.52). \n" ); document.write( "If you go strait to C and graph the equation with the given information you can also find the x intercept (in this case n intercept).\r \n" ); document.write( "\n" ); document.write( "Or you can do this algebraically, as long as you remember that the x intercept is going to be the number which makes Y=0. \r \n" ); document.write( "\n" ); document.write( "C=2.85n+30.52 \n" ); document.write( "0=2.85n+30.52 \n" ); document.write( "2.85n=-30.52 by subtracting 30.52 from both sides. \n" ); document.write( "n=-30.52/2.85 by dividing both sides by 2.85. \n" ); document.write( "This value of approximately -10.70 is your n intercept.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
