You would substitute all x's with the number 30, so the answer would be f(30)=-1 or y=-1
not sure your question?

Answer:
-4
Step-by-step explanation:
According to the rules of the distributive property, you have to multiply the term outside of the parentheses with the terms inside the parentheses first.
1. 2(-5)=-10
2. 2(3)=6
The terms that we have are now -10 and 6. Add them together to get the final answer.
-10+6=-4
I think the answer is 17. The scale is going up by two.
