<h2>
Steps:</h2>
Here are the steps to convert an equation to its inverse:
- Change f(x) to y
- Switch the positions of x and y
- Solve for y
- Change y to f^-1(x)
Firstly, do the first two steps:

Next, let's solve for y. Subtract 3 on both sides:

Next, divide both sides by 4:

<h2>Answer:</h2>
Finally, change y to f^-1(x) and your final answer will be:
, or <u>the second option.</u>
If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)
a²+b²=c²
12²+b²=15²
144+b²=225
b²=81
√b²=√81
b=9
The answer is 0.382 a liter
Answer:
43/100
Step-by-step explanation:
It would have to be 43/100 becuase 43 is a prime number, therefore it cannot be simplified.
Answer:
32000 tonnes
Step-by-step explanation:
Given there was a 20% reduction last year from a total of 40000 tonnes .
20% /100% x 40000
0.2 x 40000
8000tonnes
Therefore, previous year’s excerpt = 40000 - 8000
32000tonnes
