10y2 - 15y2 = -5y2

That would depend on the plus or minus values of 7x and 10y of which none have been given.

5(x^2 - 4xy + 2y^2)

4

(5x-9)(2x-1) when factored

10y^2 -12

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

10y plus 40 equals 50y.

10y = 9y + 4, so y = 4

Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation

maximum value of 6y+10y

It is: 7x+10y

12y2+1+15y2-10y-18y=27y2-28y+1. contact at saqibahmad81@yahoo.com

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

If you mean: -10x-10y = -20 then x intercept is at (2, 0) and y intercept at (0, 2)

yes that is correct

10x+10y+100 There is a common 10 in each number. 10(x+y+10)

10y= 6y+5+3y 10y=6+9y y=6

5y + 5y = 10y

If: x^2+y^2 = 12x-10y-12 Then: x^2+y^2-12x+10y = -12 Completing the squares: (x-6)^2+(y+5)^2 -36-25 = -12 So: (x-6)^2+(y+5)^2 = 49 Therefore the centre of the circle is at (6, -5) and its radius is 7

10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5

The greatest common factor of 10y plus 15 is 5.

8x - 7y + 6

2y+8y = 10y

y = ½ (6y = 3)
