1. Solve the system of equations algebraically. Be sure to find all
solutions!
X^2+y^2=10
2x^2-y^2=17

I got not sure if it's right or missing
x=2.999999976132
Y=0.999999870315

2. Find the coefficient of the term x^5 y^3 in the expansion of (4x-y)^8
3. Put each conic in standard form; identify the conic, , state
vertices, centers, asymptotes where applicable.
