Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.

In order to figure this out you need to use slope intercept for for each of these hills. Let's say the first hill is HA and the second hill is B
slope intercept: y = mx + b
HA: y = (2/10)x
HB: y = (2/15)x
As you can see when you plot this on a graph, HB is steeper because the line rises more sharply.
You can use proportion to solve this

Answer:

Step-by-step explanation:
<u>The Inverse of a Function</u>
Given a function f(x), the inverse of f, called
is a function that satisfies:

The domain of f becomes the range of its inverse and vice-versa.
The procedure to find the inverse of the function is:
* Write the function as a two-variable equation:
* Solve the equation for x.
* Swap the variables
We are given the function:

Defined in the interval x ≥ -3
Note f is always negative, thus its range is f(x) ≤ 0
Now we find the inverse. Call y=f(x):

Multiplying by 2:

Squaring both sides:

Subtracting 3:

Swapping variables:

Thus:

The domain of the inverse is the range of f, thus x is restricted to
x ≤ 0
