Algebra.Com's Answer #3852 by prince_abubu(198)![]() ![]() ![]() You can put this solution on YOUR website! By simply looking at it. It's linear if:\r \n" ); document.write( "\n" ); document.write( "1. There is one and only one variable that it asks you to solve for. \n" ); document.write( "2. All variables appear in the numerator. (In other words, NO variable should appear in the denominator if there is a fraction). \n" ); document.write( "3. NO variable appears inside a radical (AKA, inside a square root, cube root, etc.) \n" ); document.write( "4. The variable MUST be \"to the 1st\" power. (AKA, the variable must NOT be raised to a power. Actually by default, a variable without a power written to the \"northeast\" of it is raised to the 1st power, but that's what makes it linear). \n" ); document.write( "5. There are no trigonometric functions in it. \n" ); document.write( " |
