Using a simple guess and check method, i started with the lowest common multiple of 3, and 27 (the total growth) and used 3. if you plug i the numbers, we will say a is the dwarf lemon tree, b is the semi-dwarf lemon tree, and c is the full lemon tree, you know 3times2 equals 6. if you triple 6 you get 18. so if A grew 3 inches , B had to have grown 6 inches, and C had to have grown 18 inches. add them all and you get 27. so the dwarf lemon tree grew 3 inches, semi dwarf grew 6 inches, the full size grew 18 inches.
Answer:
By saying "paying the same rate"
I believe you want to know for example when two people are buying a product how to know if they are paying the same amount.
If so then there are a couple of factors at play.
First of all you need to identify the GDP of the product and the amount of tax/VAT which if calculated properly may help you tell if they are paying the same amount or not.
y = mx + b
m = slope
b = y-intercept
Since it is parallel to the equation y = 3x it means that the equation that goes through point (-1, 0) has the same slope (3x)
To find the b plug the x and y of point (-1, 0) into the equation: y = 3x + b then solve for b
0 = 3(-1) + b
0 = -3 + b
0 + 3 = (-3 + 3) + b
3 = b
so...
y = 3x + b
Hope this helped and made sense!

It should be A. Just factor 45
Your answer would be y=2x+1 because if you get the x and multiply the x by 2 then add 1 you get the y
