Description : Why are the equations w-x plus xw and w plus x-xw called identities?
Last Answer : w - x + x = wandw + x - x = w are true for all values of w and x and that is whythey are called identities.
Description : What equations are equivalent to 3p(p plus 2)?
Last Answer : None because without an equality sign it is not an equation butit can be simplified to 3p^2 +6p
Description : What type of lines match these equations 3x plus 2y -5 -2x plus 3y -5?
Last Answer : If you mean 3x+2y = -5 and -2x+3y = -5 then they are straightline equations
Description : What are the solutions to the simultaneous equations of y equals -2x and x2 plus y2 equals 80?
Last Answer : If: y = -2x then y ^2 = 4x^2If: x^2 + y^2 = 80 then x^2 +4x^2 = 80So: 5x^2 = 80Divide all terms by 5: x^2 = 16Square root both sides: x = -4 or +4By substitution into the original equation solutions are: (-4,8) and (4, -8)
