Zoe's unit rate is 0.625
Explanation
Just divide because remember unit rates are out of 1.
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)
Further explanation:
Given sequence is:
3, -6, 12, -24, ...
We have to find the common ratio first.
Common ratio is the ratio between two consecutive terms of a geometric sequence.
It is denoted by r.
So,
General formula for geometric sequence is:
Putting the values of a1 and r
Hence,
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)

Answer:
x= -5
Step-by-step explanation:
f(x) = [ x^2 - 25 ] / [ x + 5 ] = [ (x + 5) ( x- 5)] / [ x + 5 ] = x - 5
This will be the graph of f(x) = x - 5 with a "hole" at x = - 5
2(x - 4) - 6(2x - 3) = 0
Distribute the 2 and the 6 using the distributive property, which is: a(b+c) = ab + ac
2x - 8 - 12x + 18 = 0
Simplify
-10x + 10 = 0
Add 10 on both sides
-10x = -10
Divide -10 on both sides
-10x/-10 = -10/-10
x = 1
Your final answer is d. x = 1.
