Which set of values could be from a direct proportion?

Option 'A' is correct.

Step-by-step explanation:

Since we know that

Direct proportion means with every increase in x, there is increase in y with constant k. i.e.

So, it becomes,

A)

Here,

So, it is in direct proportion.

b)

C)

Hence, we can see that Option 'A' is correct.

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
