乖仔呀～！唔問答案～ 問解題，所以我而家極忙，都要答左你先！ ^_^ 好好學習，自己懂得解題以後就可以自己做數！ 〔１〕解句 "Express y in terms of x" 即是以 x 來表示 y。 "in terms of x" 即是「以x 的項來(做...)」 例如已知 2x+y=4，那麼 express y in terms of x 則會是答 y = 4-2x。 〔２〕解題 In a shop, the selling price of a doll is $x each. The cost of producing a doll is $(x-25). (a) If there are x2-3x+4 dolls in total, find the total cost of producing the dolls, in terms of x. (b) Find the profit gained from selling the all dolls in (a), in terms of x. 在一間店鋪中，每一個公仔賣x元，製造每一個公仔的成本是(x-25)元。 (a) 如果總共有 x2-3x+4 個公仔，求製造這些公仔的總成本，以x 表示。 (b) 求賣出(a)部份所有公仔時所獲的利潤，以x 表示。 生字： shop 店鋪 doll 公仔 produce 製造 cost 成本 profit 利潤 gain 賺得 2013-08-29 22:19:28 補充： 不打緊～ 用Chrome編輯 HTML好似有ｄ問題～ 要用番Firefox或者IE 先得～ 呢樣野唔係咁方便～ 因為我平時用Chrome 的～ 2013-08-29 22:59:42 補充： >> 同埋我想問佢想我用點樣既式去解題??? 由於沒有說明清楚, 所以係展開式(expanded form)或分解式(factorized form)都可以接受。 但記緊要化簡。 (a) (x-25)(x2-3x+4) (b) 25(x2-3x+4)
