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
Area of the cross section (Trapezium) :
1/2 (6 + 11) x 3 = 25.5 cm²
Volume = area x height = 25.5 x 3 = 76.5 cm³
Answer:
about 48 adults , because you have to divide the 477 by 10
Step-by-step explanation:
I got this question on my test and i chose this and i got it right.
I hope this helps!! :)
When using both negative symbols, and then multiplying them, this would mean that the numbers would be going up.
A negative (x's) a negative equals a positive.
Your answer: positive.
