Will only name Brainliest if its the correct answer!

Solve the system of equations. y= 2x y= x^2 - 15

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !
