The x terms add up to 4x and the numbers add up to 12
4x + 12 = 4(x + 3)
Its C
By investing in a variety of investment options
The anwser is 4.4 because you add 9+15 then add 3+2 then divied them both and thats your anwser
I am not able to see the picture
If they are proportional, then y/x should always be the same.
So 9/2= 4.5
We need to find the y value at x=3 to make y/x equal 4.5
4.5 = y/3
y = 4.5*3 = 13.5
