There is no answer to y - 2, because y - 2 isn't a question.
If you mean y/2 + y (without parentheses), y/2 is the same as (1/2)y, and y is the same as 1y. You can use the distributive property to combine this; in this case, the result is (3/2)y.
If you mean: (y-2)(y+2) then it is y^2 -4 which is the difference of two squares
y = 15 so that 13= 15 - 2 y-2 = 13 y-2 +2 = 13 +2 y = 15

X - Y = 2 When X = 3 you have 3 - Y = 2 Moving Y to RHS: 3 = Y + 2 Moving 2 to LHS: 1 = Y
2x / (y-2) + 2x / (2-y)First get a common denominator: (y-2) (2-y)Then you have:2x(2-y) / (y-2)(2-y) + 2x(y-2) / (y-2)(2-y), summing and simplifying, you get:(4x-4) / (y-2)(2-y)
If you mean y=3x-2, you can solve for x as follows: 3x-2+2 = y+2, x = (y+2)/3 = y/3 + 2/3
slope is 2 y intercept is 5/2

If x is a multiplication symbol, then square root of 36(4)y^2 = square root of(4^2)(2^2)(y^2) = (4)(2)(y) = 8y If it is a variable x, then square root of 36x4y^2 = square root of (4^2)(x)(2^2)(y^2) = (4)(2)(y)(square root of x)= 8y(square root of x)
If you mean x^4 + 3x^2 +2, then you would use any letter. Say y = x^2 therefore x^4 + 3x^2 +2 must = y^2 + 3y + 2 you can now factorise this: (y+2)(y+1) so y = -2 or y = -1 Remember, y = x^2 so, -2 = x^2. square root this. But if you remember what you've been taught, then you cannot square root a (-). So, there are no solutions. This means that the line on the graph will not intersect the x-axis. I hope this is what you are looking for.
3(4-y) = 5(y+2), what does y =
A straight horizontal line passing through y=-2
y=(x+2)/(x+10) xy+10y=x+2 xy-x=2-10y x(y-1)=2-10y x=(2-10y)/(y-1)
Given y = 2x the slope of that line is simply 2, A perpendicular line would have the negative inverse of 2, -1/2 or -.5 thus y = 2x is perpendicular to y = -.5x Y = -(1/Mx) + b is perpendicular to: Y= Mx + b
