The difference between the polynomials is 7y² + 8xy - 3
Polynomials are functions that have a degree of <u>power greater than two.</u>

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)
f(x, y) = (7y^2 + 6xy) - (-2xy + 3)
f(x, y) = 7y² + 6xy + 2xy - 3
f(x, y) = 7y² + 8xy - 3
Hence the difference between the polynomials is 7y² + 8xy - 3

C is the correct answer. The method of sampling can be considered both biased & unbiased
14x + 70(930 - x) <== ur expression
Point slope is y-y1=m(x-x1) where m is slope and x1 and y1 are the given x and y values.
y-(-1)=-3(x-7)
y+1=-3(x-7)
Final answer: B
