Which relationships have the same constant of proportionality between y and x as the equation 3y=2x? SELECT 3 ANSWERS

*Correct Question:

Which relationships have the same constant of proportionality between y and x as the equation 3y=27x?

A, B, C

Step-by-step explanation:

Given that , we can simplify to get a proportionality statement that exists between X and y. Thus

Divide both sides by 3

Thus, we can say, y would always be 9 times the quantity of x.

From the options given, examine which options have this proportionality statement as well.

Option A, y = 9x is same as the statement.

Option B, 2y = 18x, conforms to the same statement. If we simply further, we would have y = 9x

Option C, the graph shows that when x = 1, y = 9. This also confirms to the same constant of proportionality in the given equation.

Option D and E do not have same constant of proportionality.

The right options are A, B, and C.

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
