Answer:
(-5,-15)
Step-by-step explanation:
The degree of a polynomial is the highest exponent in a term
thus it'd be 7 cuz
2x^3y^4
4 + 3 = 7
Answer:
u =0
Step-by-step explanation:
55 -11u = 55
Subtract 55 from each side
55-55 -11u = 55-55
-11u = 0
Divide each side by -11
-11u/-11 = 0/-11
u =0
If we substitute z = 2 - x - y in the last 2 equations it simplifies to 2 equations in x and y:=
x^2 + y^2 + xy - 2x - 2y = 5 and
-x^2 - y^2 - xy + 2x + 2y = -5
if we add these we get 0 = 0 so there are infinite solutions
Answer:
If the 2 numbers are the same, it will be zero. If the positive number is larger than the negative number, the sum will be positive. If the negative number is larger than the positive number, then the sum will be a negative number.
