4x-10y=11 4x=11+10y 10y+11=4x 10y=4x-11 y=(4/10)x-(11/10) y=(2/5)x-(11/10)
x/10y is in its simplest form.
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
If you mean: x^2+y^2+8x-10y+5 = 0 Completing the squares: (x+4)^2+(y-5)^2 -16-25+5 = 0 So: (x+4)^2+(y-5)^2 = 36 Therefore center of circle is at (-4, 5) with a radius of 6
Ah, a lovely question indeed. In math, when we see 10y, it means we are multiplying the number 10 by the variable y. It's like having 10 happy little trees, each represented by the variable y, standing tall and proud in our equation. Just remember, math is like painting a beautiful picture, one step at a time.
