4(n-3)-(2n-8)=-2
4n-12-2n-8 = -2
2n-20= -2
+20 +20
2n= 18
/2 /2
n=9
The answer is n=9
hope this helps! :)
Answer:
The vertex is (-5,-1)
Step-by-step explanation:
f(x) = 4(x+5)²-1
This is written in vertex form
y = a(x-h)^2 +k where ( h,k) is the vertex
f(x) = 4(x- -5)²-1
H is -5 and k = -1
The vertex is (-5,-1)
