13n - 6p - 11n = 2p
2n - 6p (+6p) = 2p (+ 6p)
2n/2 = 8p/2
n = 8p/2
hope this helps
Answer:
function b
Step-by-step explanation:
When its asking for which function has a greater rate of change its asking for which slope has a greater value
the slope is calculated by change in y over change in x
for function a, as y goes up 2 x goes up 1
so the slope ( rate of change) is 2/1
for function b is y goes up 3 x goes up 1
so the slope (rate of change) is 3/1
3/1 is greater than 2/1 so function b has a greater rate of change
ANSWER
EXPLANATION
The general term of the arithmetic sequence is
For the first term,we substitute
to get,
Similarly
The sum of the first n-terms is given by the formula,
where l is the last term.
In this case
We substitute these values to get,
We could have also used the formula,
The denominators stay the same and only the numerator changes.
