Number 9 is 36 because there are 18/40 who feel safe, so it multiplied would be 36. C
1. 15-x
2. 4y
These are algebraic expressions for both.
Answer:
it's either B=6.25-1.25r or it's r=5-0.8b
Answer:
60
Step-by-step explanation:
Lets get started :)
f(x) =

- 2
y =

- 2
This is the original equation, and now we have to find the inverse.
When finding the inverse, just flip the variables, x as y and y as x
f ⁻¹(x)
↓
x =

- 2
We have to isolate y as it is our f ⁻¹(x)
Take 2 to the other side { When you see subtraction, you do addition }
x + 2 =

Take 9 to the other side { When you see division, you do multiplication }
9 ( x + 2 ) = y
9x + 18 = y
f ⁻¹ (x) = 9x + 18
