Answer: The number is: "2" . _______________________________________________________ The expression is: 2 − (½)x = (½)<span>x ; </span>→<span> in which "x" is the "unknown number". </span>_______________________________________________________ Explanation: ______________________________________________________ Given: _________________________________________________________ "Two decreased by a half of a number is one-half<span> of the number" ;
Let "x" represent the "unknown number" for which we wish to solve;
Write the expression as: _________________________________________________ " </span>2 − (½)x = (½)x " . _________________________________________________ Note: Add "(½)x" to EACH SIDE of the equation: _________________________________________________ 2 − (½)x + (½)x = (½)x + (<span>½)</span>x ;
to get: _________________________________________________ → 2 = 1x ;
↔ 1x = 2 ;
↔ x = 2 . _________________________________________________ Answer: The number is: " 2 " . _________________________________________________
Touch the x axis means the zeroes (y=0) of theh equation aka the roots aka the solutions ok, so remember that the degree of the polynomial will be the maximum number of roots so therefor minimum degreee is 5th degree
