of positive definite solutions were derived,which generalize the existing related results.A necessary condition for the existence of the equation to have only a solution and the iterative formula for this solution were obtained.Finally,we got an inverse iterative method for solving the equation.关键...
In thexy- plane, the line with equationax+by+c= 0, whereabc≠ 0, has slope . What is the value ofb? (1)a= 4 (2)c= −6 选项: 答案: A 提问列表 提问: 这个题abc不等于0只能说明任意一个数不为零,直线有斜率只能说明B不等于0,但是B的具体值怎么能通过A算出来呢?求解。
I want to count the number of non-negative solutions of the equation: ax + by = c. I know the naive approach where I can iterate over all non-negative y such that c - by is non-negative and count if c - by is divisible by a. Before starting iteration, I can...

The equation of line is ax+by+c=0. Line is perpendicular to line . The line goes through the point (2c,0). Which of the following is the equation of line ?
The equivalent integral equation of a new form for a class of fractional evolution equations is obtained by the method of Laplace transform, which is different from those given in the existing literature. By the monotone iterative method without the assu
