Answer:

You just need to demonstrate that the expression is not equivalent. To do that, we just need to evaluate the expression with a specific number.

\frac{3}{8}x+2 \neq  \frac{3}{2}x+5

For x=0, we have

\frac{3}{8}(0)+2 \neq  \frac{3}{2}(0)+5\\2 \neq 5

Notice that the answer is true because 2 is not equivalent to 5.

Therefore, the expression is actually non-equivalent.

Teresa stated that the heights of the students in her class were not a function of their ages. Which reasoning could justify Ter
jenyasd209 [6]
<h2>Answer:</h2>

Option: A is the correct answer.

A.  Two students are the same age but have different heights.

<h2>Step-by-step explanation:</h2>

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e.  age) is mapped to two or more  values i.e. corresponding y-value ( i.e.  different heights) which violates the definition of function.

Hence, option: A is the correct answer.
