Answer: 1 year

Step-by-step explanation:

1. Make an equation for both Types in standard y = mx + b form, with “b” being how tall the tree already is (so b for Type A will be 9, and b for Type B will be 2). Let “m” be equal to how many inches each tree grows per year (m for Type A will be 17, m for Type B will be 24)

2. Now you have the equations!
Type A: y = 17x+9
Type B: y = 24x+2

3. The problem is asking for how many years (represented by “x”) it will take for the trees to be of equal height, so set both of the equations equal to each other
17x+9 = 24x+2

4. Solve! (picture attached)
I hope this helped! feel free to comment if you need any clarification, though!

Answer:

12 years

Step-by-step explanation:

A = 9 ft = 108 inch

B = 2 ft = 24 inch

So, (108 - 24) = 84 inch

A 9 ft - B 2 ft = 7 ft distance

84 inch ÷ 7 feet = 12 it will take 12 years

A = 17 inch × 12 years + 108 inch = 312 inch or 26 ft

B = 24 inch × 12 Years + 24 inch = 312 inch or 26 ft
