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.
10y = 5 y = 5/10 Therefore, y = 0.5
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
6y-5=8+10y 6y-10y=8+5 -4y=13 y=-3.,25 because: 6*3.25-5=-24,5 and 8+10*3.25=-24,5 true
10y= 6y+5+3y 10y=6+9y y=6
4x-10y=11 4x=11+10y 10y+11=4x 10y=4x-11 y=(4/10)x-(11/10) y=(2/5)x-(11/10)
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
Clearly, both terms have 5 as a factor. If you divide by 5, you get the other factor:5+10y = 5(1 + 2y)This can't be further factored.
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
x2 + 10y + 25 doesn't factor neatly. If that was x2 + 10x + 25, it would factor to (x + 5)(x + 5) or (X + 5)2
2y-10y
The GCF is 5.
The greatest common factor of 10y plus 15 is 5.
