Answer: 7*N - 12
Step-by-step explanation:
Let's break this so is easier to interpret.
"12 less than a number"
if we call the number as N, this is written as:
N - 12
and the complete sentence is:
"12 less than a number times 7"
So we must multiply our number, N, by 7.
Then the expression is:
7*N - 12
Remark
The idea here is to take any two successive terms and divide one by the other. which is the divisor and which the dividend will be discussed below.
Step One
Set up the ratio for the common ratio between terms that come one after another.
Mathematically this is written as
r =
So just to see how this looks
t_(n + 1) = 3
t_n = 9
r =
r = 1/3
Does this work for other examples? Let's try a more complicated looking one.
t_(n) = 1/9
t_(n+1) = 1/27
r = t_(n + 1) / t_n
r =
r =
r = 1/3

Answer:
f(1)=<u>-2 </u> if you are saying (1,-2) is on the graph of f.
Please let me know if I misread that list of numbers you gave.
Step-by-step explanation:
I think I'm reading your question right.
You are saying that the following are points on the graph of f:
(-3,0)
(-2,2)
(0,1)
(1,-2)
The first point (-3,0) says f(-3)=0.
The second point (-2,2) says f(-2)=2.
The third point (0,1) says f(0)=1.
The last point (1,-2) says f(1)=-2.
They want to know what f(1) is... Well that is -2 since (1,-2) is on the graph of f.
