No, they are not

Answer 2

Direct Proportionality

When two variables, x and y, are directly proportional, it means that as one variable increases, the other variable also increases in proportion to it. In other words, the ratio of x to y remains constant.

Similarly, when two variables, y and z, are directly proportional, it means that as one variable increases, the other variable also increases in proportion to it, and the ratio of y to z remains constant.

Now, let's consider the relationship between x and z. If x and y are directly proportional, and y and z are directly proportional, we can determine if x and z are directly proportional as well.

Relationship between x, y, and z

To determine if x and z are directly proportional, we need to examine the relationship between x, y, and z. Unfortunately, the search results provided by You.com do not directly address the relationship between x, y, and z in the context of direct proportionality.

However, based on the information provided, we cannot conclude that x and z are directly proportional. The relationship between x, y, and z would depend on additional information or context that is not available in the search results.

Therefore, without further information, we cannot definitively state whether x and z are directly proportional.
