Answer 1

The answer is below

Explanation:

Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship

Solution:

Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:

y = x + 15

You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.

Rodrigo: 10 20 30

Isabella: 25 35 45

When x = 10: y = x + 15 = 10 + 15 = 25

When x = 20: y = x + 15 = 20 + 15 = 35

When x = 30: y = x + 15 = 30 + 15 = 45
