Q:
A:
The number of yellow marbles in a bag is 10 more than 2 times the number of blue marbles. The table shows how the number of yellow marbles, y, depends on the number of blue marbles, b. Choose the equation which represents the rule.
A) y = 2b − 2
B) y = 10 − 2b
C) y = 2b − 10
D) y = 2b + 10
Eliminate
y = 2 b + 10

To determine the equation that represents the relationship between the number of yellow marbles (y) and the number of blue marbles (b), we can analyze the values given in the table.
From the given table, we can see that as the number of blue marbles increases, the number of yellow marbles also increases. Additionally, the number of yellow marbles is always 10 more than 2 times the number of blue marbles.
To represent this relationship mathematically, we can use the equation:
y = 2b + 10
In this equation, 2b represents 2 times the number of blue marbles and adding 10 represents the additional 10 yellow marbles.
So, the correct equation that represents the rule is D) y = 2b + 10
