Answer:y=2x+4
explanation:
−10x+5y=20
Step 1: Add 10x to both sides.
−10x+5y+10x=20+10x
5y=10x+20
Step 2: Divide both sides by 5.
5y=10x+20
5. 5
Y=2x+4
R is the only one that would work. Think of it like a mirror

Answer:
43,200 serial numbers can be generated
Step-by-step explanation:
The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

How many serial numbers can be generated
3 letters, from the first five of the alphabet
3 digits, from a set of 10
So

43,200 serial numbers can be generated
