(考察范围:第十二章一元二次方程第9节由一个二元一次方程和一个二:元二次方程组成的方程组～第十三章函数及其图象第8节反比例函数及其图象.) 一、填空题(每空2分,共24分) 1.方程z。+2剁+y。=16可以化成—— 两个二元一次方程.2.方程组{zxv-+二二之的解是 lzV:=:一lU 3·函数y
(Scope of the investigation: Chapter 12: The quadratic equation of the second element. Section 9 consists of a binary equation and a bi:equalequation equation. -Chapter 13 functions and images. Section 8 Inverse-proportional functions. Image.) First, fill in the blanks (2 points for each space, a total of 24 points) 1. Equation z. +2剁+y. = 16 can be converted into two binary equations. 2. The solution of the system of equations {zxv-+ two is lzV: =: a lU 3 · function y
