Can you this is urgent? ?
if y is directly proportional to x, what is the constant of proportionality for the following table?
a. this is not a direct proportion
b. 14
c. 4
d. 2.25

B. 4

Step-by-step explanation:

A direct proportion has the form

y = kx or k=y/x,

where k is the proportionality constant.

Let's test some points.

Second point

k = 8/2 = 4

Fifth point

k = 23/5.75 = 4

You will get the same result for every point, so the constant of proportionality is 4.

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
