(only for questions 5 and 6)
5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.
6. If you substitute in b = 8, you get:

this is true.
It has a ratio of 1:4, meaning for every x, you'd get 4 from your y
3n + 5 = 6
<u> - 5 - 5</u>
<u>3n</u> = <u>1</u>
3 3
n = ¹/₃
Answer:
Step-by-step explanation:
