Answer:
The first one, an=n-2
Step-by-step explanation:
The slope of the linear equation is 1. You can notice the y intercept would be -2, therefore the equation is an=n-2.
Answer:
27 hours
Step-by-step explanation:
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2
And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5
So your final answer is A. (2, 5). I hope this helps!
