Answer:
4, 7, 10, 13, 16, 19, 22
Step-by-step explanation:
Not sure if there is more to this question but here is what I assume:
We want to find the first 7 terms of this equation given 3n+4
Assuming we are starting at 0 we plug 0 in for n.
3(0) + 4 → 4
So our first answer is 4
We continue by pugging in the next numbers after that to get to the first 7 terms
3(1) + 4 → 7
3(2) + 4 → 10
3(3) + 4 → 13
3(4) + 4 → 16
3(5) + 4 → 19
3(6) + 4 → 22
Answer:
y = -4x + 10
Step-by-step explanation:
I am going to assume you are trying to write the equation of a line.
4x + y = 10
4x - 4x + y = 10 - 4x
y = -4x + 10
