Algebra.Com's Answer #478503 by wilft1(217)![]() ![]() You can put this solution on YOUR website! solve the same way you would solve any other x,y\r \n" ); document.write( "\n" ); document.write( "where did i get the 2 from? i substituted the x for 2 and then solved for y \n" ); document.write( "look at the second one i did, i did the same thing except i substituted the x for 5 this time. thats how you get the coordinates, substitute one variable and then solve for the other.\r \n" ); document.write( "\n" ); document.write( "y=(x+3)^2-9 \n" ); document.write( "y= (2+3)^2-9 \n" ); document.write( "y= (5)^2-9 \n" ); document.write( "y= 25-9 \n" ); document.write( "y= 14\r \n" ); document.write( "\n" ); document.write( "x y \n" ); document.write( "(2,14)\r \n" ); document.write( "\n" ); document.write( "y=(x+3)^2-9 \n" ); document.write( "y=(5+3)^2-9 \n" ); document.write( "y=(8)^2-9 \n" ); document.write( "y= 64-9 \n" ); document.write( "y= 55\r \n" ); document.write( "\n" ); document.write( "x y \n" ); document.write( "(5,55) \n" ); document.write( " |
