Answer: First option.
Step-by-step explanation:
You know that the function represented by the equation is the following:
Then, you can follow these steps in order write the equation in function notation with "x" as the independent variable:
1. Solve for "y":
Add to both sides:
Add 9 to both sides:
2. Since is a common way of representing "y", you get:
Answer:
C is correct.
Step-by-step explanation:
At a picnic,
Number of adults is 3 times as number of children.
Number of women is twice as number of men.
Total number of men, women and children at the picnic be x
Let number of children be c
Let number of men be m
Let number of women be w
# Number of women is twice as number of men, w = 2m
# Number of adults is 3 times as number of children, w + m = 3c
2m + m = 3c (∴ w=2m )
c = m
Total number of men, women and children at the picnic be x
∵ c + m + w = x
m + m + 2m = x
4m = x
Number of men,
Hence, The total number of men will be
