4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)
5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)
equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2
substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1
The values of x and y are -2 and -1 respectively.
<span>So we have a polynomial 5x^5-9x^3+2x^11+6 and we are wondering what is its degree, leading coefficient, number term and the constant term. The degree of a polynomial is its highest power so here that is 11. Leading coefficient is the term with the highest degree of a polynomial and here thats 2. Number of terms is 4 because that many numbers are in this polynomial and the constant term is 6 beccause it is a constant. </span>
