Answer:
f(3) = -11
Step-by-step explanation:
f(3) means you sub the value that is inside into x
f(3) = -3(3) - 2
= -9 - 2
= -11
A) (x-4)(x-16)=x^2-16x-4x+64=x^2-20x+64
b) (x-8)(x-8)=x^2-16x+64
c) (x+8)(x+8)=x^2+16x+64
d) (x+4)(x+16)=x^2+20x+64
The given expression is x^2+16x+64, it is same as c)
The final answer is c) (x+8)(x+8)
Answer: The 9th term is 6561
Step-by-step explanation:
The geometric sequences have the following formula
Where 
is the first term of the sequence and r is the common ratio between the consecutive terms of the sequence
In this case the sequence is 1 -3 9 -27
So 
Observe that the common ratio r is:
So the formula is:
We want to find 
ANSWER:
C) (2, 5)
STEP BY STEP EXPLANATION:
You have to change it from point slope form to slope intercept form. then you have to substitute the ordered pairs for x & y & it'll show if it's a true statement or if it's a false statement.
y - 2 = 3(x - 1) --- POINT SLOPE FORM
y - 2 = 3x - 3
+ 2 + 2
y = 3x - 1 --- SLOPE INTERCEPT FORM
A: (-2, -2):
y = 3x - 1
-2 = 3(-2) - 1
-2 = -6 - 1
-2 = -7
NO
B: (-1, -2):
y = 3x - 1
-2 = 3(-1) - 1
-2 = -3 - 1
-2 = -4
NO
C: (2, 5):
y = 3x - 1
5 = 3(2) - 1
5 = 6 - 1
5 = 5
YES
Hope this helps you!!! :)
It’s 10, or it could be -10 it doest matter it will still end up being 10
