Question Help Writing Suppose the relationship between x and y is proportional. When x is 29, y is 275.5. Find the
constant of proportionality of y to x. Use the constant of proportionality to find x when y is 408.5. Use
pencil and paper. Explain how you can tell a relationship that is proportional from a relationship that is
not proportional.
The constant of proportionality is I.
(Type a whole number or a decimal.)

a) I=9,5

b) x=43

c) I is same for every  value of y and x if the relationship is proportional.

Step-by-step explanation:

The constant of proportionality I can be found as:

a)

We are given: x= 29, y=275.5 we need to find constant of proportionality I

Using formula:

So, constant of proportionality I = 9.5

b)

Now, we need to find x when y is 408.5.

Using the above formula we can find x

c)

A relationship is proportional if for every value of x and y we have a relation: where I is constant. The value of I is same for every value of y and x.

If a relationship is not proportional then for every value of x and y we have don't have a relation: where I is constant. The value of I is different for every value of y and x.

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
