Answer:
"Prime Factorization" is finding which prime numbers multiply together to make the original number.
Here are some examples:
Example 1: What are the prime factors of 12 ?
It is best to start working from the smallest prime number, which is 2, so let's check:
12 ÷ 2 = 6
Yes, it divided exactly by 2. We have taken the first step!
But 6 is not a prime number, so we need to go further. Let's try 2 again:
6 ÷ 2 = 3
Yes, that worked also. And 3 is a prime number, so we have the answer:
12 = 2 × 2 × 3
As you can see, every factor is a prime number, so the answer must be right.
Note: 12 = 2 × 2 × 3 can also be written using exponents as 12 = 22 × 3
Answer:
y = 5x+15
Step-by-step explanation:
The cost per calculator is 5
The shipping cost is 15
Let y = total cost
Let x = number of calculators
y = 5x+15
Answer:
A
Step-by-step explanation:
Answer:
160 nickels, 80 pennies
Step-by-step explanation:
160 nickels = $8
80 pennies = $0.80
$8 + $0.80 = $8.80
Answer:
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1
Step-by-step explanation:
Initially:
We have the function 
k(x + 1)
To translate a function k(x) a units to the left, we find k(x + a).
Thus, k(x+1) is the translation of k(x) 1 unit to the left.
-k(x+1)
Multiplying a function by a negative constant is the same as reflecting it over the x-axis, and then scaling it vertically by a factor of the constant.
Thus:
The answer is given by option A:
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1
