Answer:
4x+y add like terms ... -5+9=4 and -y(or -1)+2y=y
Yes.
The prime factorization is ...
84 = 2² × 3 × 7
Answer:
4/15
Step-by-step explanation:
Answer:
The function is f(x) = x + 2 when x > 4 and
x when x = 4
Step-by-step explanation:
Given - There were 4 people at the starting meeting. If those 4 people told
2 people about the march, and those 2 people told another 2,
To find - How would we write this function?
Proof -
As given, initially , Total number of people = 4
After that, those 4 people told 2 people about the march
This means,
Total people know about the march = 4 + 2 = 6
Now,
Those 2 people told another 2
This means,
Total people know about the march = 6 + 2 = 8
∴ we get
The function is f(x) = x + 2 when x > 4 and
x when x = 4
