In order to solve it you must make each component negative. Multiply them by negative one!
M < 2
Now which numbers would satisfy it? M is less than two... so, m could be one, or any negative number, yeah?
Multiply by negative one. - M and -2 are what you have. If it were one... negative one is less than negative two. Turns out M is less than two.
M < 6
M is less than six. It could be 1, 2, 3, 4, or 5.
-M and -6
Is negative 3 less than -6? All of the numbers are! So, m is actually less than 6
brand A 7.79. 8 cent brand B 6.83 7 cent
Step-by-step explanation:
better buy brand B you get twice much and they are 1 cent cheaper
187÷24=7.79 /287÷42=6.83
Since there are 24 fiction books and 52 books in total, you can start with subtracting them both to find the amount of non-fiction books. 52-24=28, so 28 non-fiction books are currently checked out. Now for the fun part. There are two ways I know how to do this, so let's start. One way is that you can put a ':' between the two numbers. For example, since we are trying to find fiction books to non-fiction, we would say 24:28. The first number will represent the first thing they ask for (fiction), and the second number will represent the second thing they ask for (non-fiction). Another way to do this is by putting the numbers as a fraction. For example, you could put 24/28. It will still mean the same thing, and it will not change the outcome. I hope this helps! :)
16x² - 8x + 1 = (4x)² - 2 · 4x · 1 + 1² =(4x - 1)²
Used: (a - b)² = a² -2ab + b²
