That would be 4 :D , basically 12 divided by 3
I'm not 100% sure what the question wants as its answer, but having a class of 26 students is around the average number of students in a class.
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:
5y + 15x = 25, 9x - y = -4
Step-by-step explanation:
The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:
1. y = (-3/5)x + 5
2. y = 9x + 4
For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.
For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4
