Answer 1

Answer:

• 1. D
• 2. C

Step-by-step explanation:

1. .....................................................................................................

A. This is a functional relationship as the number of workers depend on the number of job sites.

• y = 5x

B. This is a functional relationship as the amount of money is dependent on the number of withdrawals

• y = 2500 - 200x

C. This is a functional relationship as the number of vitamins depend on the number of monkeys

• y = 3x

D. This is NOT a functional relationship as the output is a fixed value. The performance and scoring may repeat.

2. .....................................................................................................

Given

• A = 62x -100
• B = 2x - 3

To find

• A/B

Solution

• A/B =
• (62x - 100)/(2x - 3) =
• (31*2x - 31*3 - 7)/(2x - 3) =
• (31(2x - 3) -7)/(2x - 3) =
• 31 - 7/(2x - 3)

Correct option is C.
