2xy=2*30*2=120
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
15xy-2xy-7x+x=13xy-6x
-2
No, it equals -2xy. lrn2math
It's an hyperbola equation.
Assuming y' is dy/dx, y = x^4/4 + yx^2
the graph is moved down 6 units
the difference between 2x2 +4xy-3 and x2-2xy-4 is?
(2xy-4x)+ (8y-16)=2xy-4x+8y-16, which factors as 2(x+4)(y-2)
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
