Answer:
y is directly proportional to x
<u>y=kx</u>, where k is a constant
Now, y=12 when x=15
When x=2,
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.

easy
because it can be written in the <u>form</u><u> </u>of p/q
Where p and q are integers, and q is <u>not</u> equal to zero.
x=4
13x+1 = 11x+9
13x-11x = 9-1
2x = 8
x = 4
