Question

Solve the system of equation algebraically
(x+2)^2+(y-16)^2=1
y=-4x+8

Answer 1

in this i foiled the first set, and after pluging in -4x+8 as y, i foiled the second part of the first set. it comes to be 17x^2+68x+67=0. I dont know what to do after that.

Answer 2

you can use the general formula.

Answer 3

i dont know how

Answer 4

\[17 x^2+68 x+67 \]cannot be factored. Use the quadratic formula:

Answer 5

i dont know how
all i know is the outcome from the quadratic formula, not weather it is x or y, and how to get the other one from it
