Answer:
x = -6
Step-by-step explanation:
Answer:
f(x)=(x-3)^2-7
Step-by-step explanation:
Vertex form: f(x) = a(x-h)^2+k
x^2-6x+9+2=f(x)+9
(x-3)^2+2=f(x)+9
f(x)=(x-3)^2-7
Uhhhh... I think you just said it, elsewhere, 7 * b - 3
Step-by-step explanation:
18/x is the same as 18•x-¹
derivative of ax^n=n•ax^n-1
derivative of 18•x-¹= -1•18•x-²
= -18x-² which is the same as -18/x²
hence 2-18/x²
180-65 = 115
6x + 7 = 115
6x= 108
x= 108/6
x=18
