Answer:
X= -7 ± √17 / 16
x= - 0.7798...
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Multiplying the first equation by xy, we have ...
x^2 +y^2 = -xy
Factoring the expression of interest, we have ...
x^3 -y^3 = (x -y)(x^2 +xy +y^2)
Substituting for xy using the first expression we found, this is ...
x^3 -y^3 = (x -y)(x^2 -(x^2 +y^2) +y^2) = (x -y)(0) = 0
The value of x^3 -y^3 is 0.
Uh i dont know are you supposed to add or substract multiply or divid use nixed numbers on no mixed numbers
1 1/1 is the fraction, because ...........
