To determine if the expressions (5x - 3xy - 5x) and (7xy - 4y) are equivalent, we can simplify the first expression. Simplifying (5x - 3xy - 5x) results in (-3xy). The second expression, (7xy - 4y), does not simplify to (-3xy). Therefore, the two expressions are not equivalent.
(xy - 7)(x^2y^2 + 7xy + 49)
5x(7xy + 6x + 8)
-7xy(x4y2 + 6x2y - 5)
No, the expression (7xy - 11) is not a linear equation because it contains the product of two variables, (x) and (y). A linear equation in two variables typically has the form (Ax + By + C = 0), where the variables are not multiplied together. In this case, the presence of the term (xy) indicates that the equation is nonlinear.
It is: 7xy/21yz = x/3z when simplified

(xy - 7)(x^2y^2 + 7xy + 49)
-9x^2 - 15x
The GCF is 7xy^3
5x(7xy + 6x + 8)
A quadratic. For example, x^2 + 3x - 7xy - 12y - 25 = 0
1xy
-7xy(x4y2 + 6x2y - 5)
gcf(35x², 7xy², 21x²y²) = 7x 35x² = 5 times 7 times x² 7xy² = 7 times x times y² 21x²y² = 3 times 7 times x² times y² hcf = 7 times x = 7x (I've written the multiplication as times instead of using the × symbol to avoid confusion with the unknown x.)
