y=5/4xNow let x =-4, x = 0, and x = 4, and find the corresponding values of y. Graph the equation.In the previous two examples we began by picking values for x. We could just as easily have chosen values for y.EXAMPLE 3 Graph 3x-4y = 12....
12.4x−2y+5=0⇒y=2x+52,若两个图象没有交点,即方程2x+52=x2−4x+k⇒x2−6x+k−52=0没有实数解,故考虑判别式︰62−4(k−52)<0,36−4k+10<0,4k>46,k>1112.由此可得k的最小整数值为12.相关推荐 1已知在平面直角坐标系中y=x2−4x+k与4x−2y+5=0的图象没有交点,求...

The roughly 4x faster latency avoiding miner uses 33 bits per edge and is bottlenecked by bucket sorting, making it memory bandwidth bound. Dynamic Sizing Instead of fixing n, a proof-of-work system could allow miners to work on any graph size they like, above a certain minimum. Cycles in...

Formally, a function f: X → Y is equivariant with respect to a group G that acts on X and Y if: $${D}_{Y}[g]f(x)=f({D}_{X}[g]x)\quad \forall g\in G,\forall x\in X$$ (1) where DX[g] and DY[g] are the representations of the group element g in the...
