Solving the simultaneous equations works out as x = -2 and y = -2
So the lines intersect at: (-2, -2)
They are: x and y and the expression can be simplified to 6xy
Without an equality sign it is not an equation
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
I will assume that you mean -2xy3+3x2y. Then by "degree" is usually meant the total degree--the maximum sum of exponents of all variables. Here the first term has degree 1+3=4 and the second term has degree 2+1=3, so the degree of the entire expression is 4. It is also a 2nd degree expression in x and a 3rd degree expression in y.
(3 * 3)(2 * 5) (9)(10) 90
They are: x and y and the expression can be simplified to 6xy
3x2y
12
It is a polynomial in x and y.
The GCF is 3x2y
Without an equality sign it is not an equation
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
3x2y - 4xy + 4x
2y-6=3x2y-3x-6=0-3x-6=-2y3/2x+3=yy-inercept= 3slope= y(2)-y(1)/x(2)-x(1)= 6-3/2-0= 3/2
Say the Question is 3(2y+5) Multiply both terms in the brackets by 3 so (3x2y)+(3x5) = 6y+15
