Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y + 2x3y4 + xy3? a) both the sum and difference have a degree of 6. b) both the sum and difference have a degree of 7. c) the sum has a degree of 6, but the difference has a degree of 7. d) the sum has a degree of 7, but the difference has a degree of 6.

3x^5y - 2x^3y^4 - 7xy^3 - 8x^5y + 2x^3y^4 + xy^3 =

-5x^5y - 6xy^3

3x^5y - 2x^3y^4 - 7xy^3 + 8x^5y - 2x^3y^4 - xy^3 =

-4x^3y^4 + 11x^5y - 8xy^3

C) The sum has a degree of 6, but the difference has a  degree of 7.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
