The equation given is:
15x - 3y = 21
Slope intercept form is:
y = mx + b
15x - 3y = 21
-15x -15x
-------------------
-3y = -15x + 21
/-3 /-3 /-3
---------------------
y = 5x -7
The answer is: y = 5x - 7

Answer:

Step-by-step explanation:
<u>Recursive sequence
</u>
In a recursive sequence formula, each term
is computed as a function of one or more previous terms. In the formula

n is the number of the term we want to calculate. If n=8, then the formula becomes

We can see
is the previous term. It means we need
to be able to compute
. But we also need
to compute
and so on until some known data is reached. The question provides five terms,

Answer:

Step-by-step explanation:
Hello,


It means that

And we know that

So we got two equations

For 
For 
I assume that we are after two different roots so the solution for p is p=-11
b) 
So a quadratic equation with the expected roots is

Hope this helps.
