An equation does not need variables. 4+5=9 is an equation as is 5+W=9
Assuming the point is (9, -4), the equation is y = -4.
The straight line equation works out as: 3y = x
Equation of circle: (x-2)^2 +(y+9)^2 = 49
The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
(2y + 5)(y - 9)
(x - 13y)(x + 13y)
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
-26x
It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.
(y2+13y+22)/(y+2) = (y+11)
y= -3/13​​
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
