That equals 2xy + 3y which factors to y(2x + 3)
No translation will invert a quadratic graph.
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
y=-10x-4
yes 3xy=6
no
No, it is not.
x = -1 y = 2 2x3 - 3xy = 2 (-1)3 - 3(-1)(2) = 2 (-1) - (-6) = -2 + 6 = 4 Suggestion: Please be careful around problems like this until you have some more experience.

2x^2+3xy-4y2(4)+3(2)(-4)-(4)(-4)8-24+16=0
3xy - 3xy = 0
(x + 6y)(x - 3y)
y=6
the graph is moved down 6 units
Whooop!
The graph is a circle with a radius of 6, centered at the origin.
