document.write( "Question 356211: hi, my daughter is doing a lesson called \"graphing a line given its equation in slope-intercept form\"..there are 2 problems she left blank and i can't figure out what to do...how would you write the equations for these problems?......1) The temperature is -6 degree celcius and rising at a rate of 2 degree per hour? 2) The temperature is 12 degree celcius and dropping at a rate of 3 degree per hour? can you also please show it on graph. thank you \n" ); document.write( "
Algebra.Com's Answer #254268 by mananth(16946)![]() ![]() You can put this solution on YOUR website! y = temperature at any given time t. \n" ); document.write( "temperature increase 2 deg /hour \n" ); document.write( "in t hours it will increase by 2t deg. \n" ); document.write( "now it is -6 \n" ); document.write( "so the equation for temperature at any given time later will be \n" ); document.write( "y = -6 +2t \n" ); document.write( "... \n" ); document.write( " \n" ); document.write( "you will observe after 3 hours temperature = 0 , y=0 \n" ); document.write( "... \n" ); document.write( "Similarly \n" ); document.write( "y = 12-3t \n" ); document.write( " \n" ); document.write( " after 4 hours y=0 Or temperature = 0 \n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
