65/100(y-1)=37/100(y+1)+0.1
65/100(y-1)=37/100(y+1)+0.1
65/100(y-1)=37/100(y+1)+0.1
5/100(y-1)=37/100(y+1)+0.1
0.65y-0.65=0.37y+0.37+0.1 0.28y=0.65+0.37+0.1=1.12
y=1.12/0.28
y =4
但愿能帮到你,祝你学习进步,不懂再问O(∩_∩)O~
0.65y-0.65=0.37y+0.37+0.1
0.28y=0.65+0.37+0.1=1.12
y=1.12/0.28=4
65/100(y-1)=37/100(y+1)+0.1
w=(d 2*m 3*(m 1)/5 y y/4-y/100 y/400
65/100 (y-1)= 37/100 (y+1)+0.1/=分数线
一段matlab的简单程序function dy=ch(t,y)dy=zeros(3,1);dy(1)=100-100*0.2*y(1)-0.2*y(1)*y(2)+100-0.0003*y(1)-0.002*y(1);dy(2)= 100+100*0.2*y(1)+0.2*y(1)*y(2)-0.2*y(2)*y(3)-0.0003*y(2)-0.002*y(2);dy(3)=100+0.2*y(2)*y(3)-0.0003*y(3)-0.002*y(3);func
65%(y-1)=37%(y+1)-0.1
求导:Y=(3X^4-1)^100 求y’
328-y/y x 100%=-18%
10X+Y+1/3Z=10Y+X 10X+Y+2/3Z=100X+Y
还有这个 int week=(d+2*m+3*(m+1)/5+y+y/4-y/100+y/400)%7;
x+y=100 2x=2/1y=92 X,Y得多少
不解方程组2x-y=10 x+3y=1/100 求(2x-y)²-(2x-y)²(x-4y)的值
二元一次方程应用问题 100(90-y)+y=100y+(90-y)+2178
100/(x-y)+100/(x+y)=100/y 怎么解100/(x-y)+100/(x+y)=100/y 怎么解出 x=(1+根号2)y
1:4(x-100)+3y=5 2:6(x-y)-2(x+y )=14 x-100=-y 3(x-y)+(x+y)=5 先无视上面的1.4(x-100)+3y=5x-100=-y2.6(x-y)-2(x+y )=143(x-y)+(x+y)=5
二元一次方程帮忙解下(1)12.5x+13.3y-200=12x+13.5y12.9x+13.9y-1300=12.5x+13.3y x=?y=?(2)200x+150y=5500150x+100y=4000 x=?y=?(3)x+y=68100x+y-100y-x=2178 x=?y=?
方程y''=(1+y'*y')/2y的通解
已知x和y是两个正整数,其 中:(x×y)+(x÷y)+(x+y)+(x-y)=100但是x不等于25,y不等于1,求x=?;y=?
二阶微分方程.100y'' + 140y' + 49y = 0已知:y(0)=0; y'(0)=7y(x) 以及 y(x)的最大值.
