If xx and yy are in direct proportion and yy is 4 when xx is 6, find yy when xx is 3.
Answer
Attempt 1 out of 2
y, equalsy=
y = kx
To find the constant of proportionality (k), we will use the given values xx=6 and yy=4:
4 = 6k
k = 4/6
k = 2/3
Now that we have the value of k, we can find yy when xx is 3:
y = (2/3) * 3
y = 2
Therefore, when xx is 3, yy is 2.
