The answer is C. Multiplication
Answer:
This is true!
Step-by-step explanation:
It is natural because it is a positive integer greater than 0, it's whole because its not negative and it is an integer.
1. -1•5•5 or also -1•5²
2. -1•7•7 -1•7²
3. -1•7
4. -1•13
5. -1•2•2•2•3 -1•2³•3
6.-1•2•2•2•2•3 -1•2^4•3
7. -1•2•2•2•3•7 -1•2³•3•7
Both factorization are correct it just depends on your teacher how she/he wants you to write it.
Answer:
1) To determine how much the change of $9,000 to $10,395, we must subtract 9,000 from 10,395;
10,395 - 9,000 = $1,395 is the change in <u>price</u> (an increase).
Formula to find percentage of change;
Change in price/original amount x 100% (100/100)
Replace those values:
1,935 (change in price/increase) 100
_____ x _____ =<u> </u><u>%0.215</u>
9,000(original amount) 100
Answer: C) All real values of x such that 
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
