X = 3 and x = -1 are the answers for both. They are exactly the same equation.
FOR COMPLETING THE SQUARE
Make in terms of ()^2 which you can do by adding numbers to both sides. Eventually it will look like this:
(2x - 1)^2 - 7 = 0
Add to both sides, take a square root and then solve.
USE THE QUADRATIC FORMULA
Be sure to solve for zero and be aware of negatives when plugging in.
Answer:
f^-1(x)=w-3
Step-by-step explanation:
1. switch c with f
f=w+3
2. switch w and f
w=f+3
3. solve for f
f=w-3
4. Switch f with f^-1(x)
f^-1(x)=w-3
The correct answer choices are B and C.
Here is the way these numbers would fall on a vertical number line justifying why these 2 answers are correct.
-1500 A
-1600
-1700
-1800
-1900 B
-2000
-2100
-2200
-2300 C
You can see where each of these submarines is located. 0 is sea level.
Well all you have to do is input 18027 * 1003 into your calculator, formerly known as 18027 multiplied by 1003 which gives us 18081081x
