Find 
First, we calculate the inverse function
Express f(x) as y
Swap the positions of x and y
Solve for y: Add 4 to both sides
Square both sides
Divide both sides by 2
Express y as an inverse function
Next, solve for:
Substitute 6 for x
If it was 20 inches x 10 inches the perimeter would be 60 inches. which is the smallest possible perimeter with whole numbers

<span>"A TV is on sale at 30% off for $420"
What was the original price of the TV?
</span>
Well if you start to calculate first off you are sooner or later going to figure out that in order for it to be 420 the answer has to be bigger than 1,000. If you get to 1,200 and calculate 30 percent off of it it the answer is 360 so a ballpark quesstiminate would be to go two more hundredths up. Therefore 30 percent of 1,400 is 420
Answer:
This is true
Step-by-step explanation:
Take for example 10=5x, you would divide both sides by 5 without changing anything to the equation.
In a case like 5=0x, you can't divide both sides by 0, so the solution is undefined.
