Step-by-step explanation:
Since y is directly proportional to x,
we have y = kx, where k is a real constant.
When x = 15, y = 12.
=> (12) = k(15), k = 0.8.
Therefore we have y = 0.8x.
When x = 2, y = 0.8(2) = 1.6.
The answer is y = 1.6 when x = 2.
Answer:
-2
Step-by-step explanation:
Step-by-step explanation:
C=b/a
c=kb/a
where as k is the constant
c=kb/a
we substitute
33=22k/6
crossed multiply
33*6= 22k
198=22k
we divide both sides by 22
198/22=22k/22
K=9
