Question 1
The table shows the age relationship between Jamie's cat and dog.
Which equation gives this relationship? Let c represent the cat's age and d represent the dog's age.
Responses
A c = d + 4c = d + 4
B d = c + 4d = c + 4
C c = d + 3c = d + 3
D d = c + 3
11 answers
A) c = d + 4
how do you know?
We know that c represents the cat's age and d represents the dog's age. The table shows the age relationship between the cat and dog, and we need to find the equation that represents this relationship. In the table, the cat's age is always 4 years older than the dog's age. This can be represented by the equation c = d + 4, where c is the cat's age and d is the dog's age.
this is the graph
Cat (c) Dog (d)
1 4
2 5
3 6
4 7
Cat (c) Dog (d)
1 4
2 5
3 6
4 7
I apologize for the confusion. Based on the given graph, we can determine the equation by observing the pattern of the relationship between the cat's age (c) and the dog's age (d).
Looking at the table, we can see that the difference between the cat's age and the dog's age is always 3. In other words, the cat's age is always 3 years less than the dog's age.
Therefore, the correct equation that represents this relationship is:
c = d - 3
So the correct answer is:
D) d = c + 3

Therefore, the correct equation that represents this relationship is:
c = d - 3
So the correct answer is:
D) d = c + 3

A relation describes a function if each input has only one output.
Looking at the given options:
A) This relation does not describe a function because both x = 0 and x = 2 have multiple outputs (y = 0 and y = 2).
B) This relation does not describe a function because both x = -2 and x = 3 have multiple outputs (y = -3 and y = 2).
C) This relation does not describe a function because both x = 2 and x = 3 have multiple outputs (y = -1 and y = 1).
D) This relation does describe a function because for each unique x-value, there is only one y-value.
E) This relation does not describe a function because x = 4 has multiple outputs (y = 3 and y = 14).
Therefore, the relation that describes a function is:
D) {(2, 2), (2, 3), (3, 2), (3, 3)}
