2015年6月3日 · Given xy = 1/5 multiplying x by a factor of k results in the need to divide y by k to maintain the equality. Therefore the equation is an inverse variation.

2018年5月18日 · The expansion is -y^5+5y^4x-10y^3x^2+10y^4x^3-5y^5x^4+x^5. We need to use Pascal's Triangle, shown in the picture below, for this expansion.

2016年10月11日 · Find at least two pair of coordinates that satisfy the equation; plot those points; draw a line through the points.

2017年7月21日 · x^5-y^5=(x-y)(x^4+x^3y+x^2y^2+xy^3+y^4) We know that : x^n-y^n=(x-y)(x^(n-1)+x^(n-2)y+...+xy^(n-2)+y^(n-1)) So let's use this : x^5-y^5=(x-y)(x^4+x^3y+x^2y^2+xy^3+y^4)

2016年3月13日 · #xy =5- p# #y =(5- p)/x# Answer link. Related questions. How do you know which formulas to use when ...

2016年12月3日 · Please see below. The equation given here x^2-4xy+4y^2+5sqrt5+1=0 is of the form Ax^2+Bxy+Cy^2+Dx+Ey+F=0. What a rotation does is it changes x & y-axes to x' & y'-axes, as shown below,. In such a case, the relation between coordinate (x,y) and new coordinates (x',y') is given by x=x'costheta-y'sintheta and y=x'sintheta+y'costheta and reverse is …

2017年11月9日 · Differentiate xy=5, w.r.t . #x dy/dt + y dx/dt =0# Now, given x=3, y would be #5/3#.

2016年7月26日 · Since (-1,-1) is not a point on the given curve, this question has no solution as it stands. However the slope of xy^5+x^5y=2 at (-1,-1) is -1. Differentiate both sides of the equation xy^5+x^5y=2 with respect to x leads to {dx}/{dx} y^5+x {dy^5}/{dx}+{dx^5}/{dx} y+x^5 {dy}/{dx} = 0 or y^5 +5xy^4 {dy}/{dx} +5x^4y+x^5 {dy}/{dx} = 0 So that at (-1,-1) we have (-1)^5+5(-1)(-1)^4 …

2017年1月3日 · Get the x-intercept by setting y=0 and solving for x. Get the y-intercept by setting x=0 and solving for y. Graph these two points, and connect them. An intercept is simply a point where a line (or any function) crosses an axis. At such a point, the non-axis coordinate is 0. (e.g. all points on the x-axis have no displacement in the y direction, so the y-coordinate is 0.) We …

log_5((xy^3)/z^4) = log_5(x)+3log_5(y)-4log_5(z) Source numbers multiplied -> add logs Source number to power -> power x log of number Source numbers divide a/b-> log(a)-log(b) Using the above and not changing the base of the log: log_5((xy^3)/z^4) = log_5(x)+3log_5(y)-4log_5(z)
