x is directly
proportional to y. x=12 while y=4. Find y when x is 69.
Solution
x ⍺ y
x = ky
12 = k x 4
12 = 4k
4 4
k = 3
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
k = 3, y= ? x =
69.
x = ky
69 = 3 x y
69 = 3y
3 3
y = 23.
TRY THIS…………….
x is directly proportional to y. x=28 while y=4. Find y when
x is 70.
